Enable Configuration Change Alerts When set, Cloudera Manager will send alerts when this entity's configuration changes. false enable_config_alerts false
Service Triggers The configured triggers for this service. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific service.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger fires if there are more than 10 DataNodes with more than 500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleType = DataNode and last(fd_open) > 500) DO health:bad", "streamThreshold": 10, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.

Hadoop User Group Mapping LDAP Bind User Distinguished Name Distinguished name of the user to bind to AD as for user authentication search/bind and group lookup for role authorization. For openLDAP based directories this should be a DN string, for Active Directory this can be just a username, combined with the "Active Directory Domain" value for login. For example username in the field and example.com in the active directory domain will result in the User Principal Name value of username@example.com being used to bind. If you put a UPM value here, do not over-configure the "active directory domain" field otherwise you will end up presenting username@example.com@example.com for binds. AD will accept a UPN value or the DN value as a valid Bind DN; An example of a Distinguished Name (DN): CN=cdh admin,OU=svcaccount,DC=example,DC=com An example of a UPN value: cdhadmin@example.com hadoop.security.group.mapping.ldap.bind.user hadoop_group_mapping_ldap_bind_user false

Log and Query Redaction Policy Note: Do not edit this property in the classic layout. Switch to the new layout to use preconfigured redaction rules and test your rules inline.Use this property to define a list of rules to be followed for redacting sensitive information from log files and query strings. Click + to add a new redaction rule. You can choose one of the preconfigured rules or add a custom rule. When specifying a custom rule, the Search field should contain a regular expression that will be matched against the data. If a match is found, it is replaced by the contents of the Replace field.Trigger is an optional field. It can be used to specify a simple string to be searched in the data. If the string is found, the redactor attempts to find a match for the Search regex. If no trigger is specified, redaction occurs by matching the Search regular expression. Use the Trigger field to enhance performance: simple string matching is faster than regular expression matching.Test your rules by entering sample text into the Test Redaction Rules text box and clicking Test Redaction. If no rules match, the text you entered is returned unchanged. redaction_policy version: 1, rules: [ description: Redact passwords from json files, trigger: password, search: \password\[ ]*:[ ]*\[^\]+\, caseSensitive: false, replace: \password\: \LOG-REDACTED\ , description: Redact password\u003d and password:, trigger: password, search: password[:\u003d][^ \\\\\]+, caseSensitive: false, replace: password\u003dLOG-REDACTED , description: Redact passwd\u003d and passwd:, trigger: passwd, search: passwd[:\u003d][^ \\\\\]+, caseSensitive: false, replace: passwd\u003dLOG-REDACTED , description: Redact pass\u003d and pass:, trigger: pass, search: pass[:\u003d][^ \\\\\]+, caseSensitive: false, replace: pass\u003dLOG-REDACTED , description: Redact PASSWORD, , trigger: PASSWORD, , search: PASSWORD, [^\\\\\]+, caseSensitive: false, replace: PASSWORD, LOG-REDACTED , description: Redact secret\u003d and secret:, trigger: secret, search: secret[:\u003d][^ \\\\\]+, caseSensitive: false, replace: secret\u003dLOG-REDACTED , description: Credit Card numbers (with separator), search: \\d4[^\\w:]\\d4[^\\w:]\\d4[^\\w:]\\d4, caseSensitive: true, replace: XXXX-XXXX-XXXX-XXXX , description: Social Security numbers (with separator), search: \\d3[^\\w:]\\d2[^\\w:]\\d4, caseSensitive: true, replace: XXX-XX-XXXX ] redaction_policy false

Heap Dump Directory Path to directory where heap dumps are generated when java.lang.OutOfMemoryError error is thrown. This directory is automatically created if it does not exist. If this directory already exists, role user must have write access to this directory. If this directory is shared among multiple roles, it should have 1777 permissions. The heap dump files are created with 600 permissions and are owned by the role user. The amount of free space in this directory should be greater than the maximum Java Process heap size configured for this role. oom_heap_dump_dir /tmp oom_heap_dump_dir false

Automatically Restart Process When set, this role's process is automatically (and transparently) restarted in the event of an unexpected failure. This configuration applies in the time after the Start Wait Timeout period. false process_auto_restart true
Enable Metric Collection Cloudera Manager agent monitors each service and each of its role by publishing metrics to the Cloudera Manager Service Monitor. Setting it to false will stop Cloudera Manager agent from publishing any metric for corresponding service/roles. This is usually helpful for services that generate large amount of metrics which Service Monitor is not able to process. true process_should_monitor true
Process Start Retry Attempts Number of times to try starting a role's process when the process exits before the Start Wait Timeout period. After a process is running beyond the Start Wait Timeout, the retry count is reset. Setting this configuration to zero will prevent restart of the process during the Start Wait Timeout period. 3 process_start_retries false
Process Start Wait Timeout The time in seconds to wait for a role's process to start successfully on a host. Processes which exit/crash before this time will be restarted until reaching the limit specified by the Start Retry Attempts count parameter. Setting this configuration to zero will turn off this feature. 20 process_start_secs false

Metric Filter Defines a Metric Filter for this role. Cloudera Manager Agents will not send filtered metrics to the Service Monitor. Define the following fields:
  • Health Test Metric Set - Select this parameter to collect only metrics required for health tests.
  • Default Dashboard Metric Set - Select this parameter to collect only metrics required for the default dashboards. For user-defined charts, you must add the metrics you require for the chart using the Custom Metrics parameter.
  • Include/Exclude Custom Metrics - Select Include to specify metrics that should be collected. Select Exclude to specify metrics that should not be collected. Enter the metric names to be included or excluded using the Metric Name parameter.
  • Metric Name - The name of a metric that will be included or excluded during metric collection.
If you do not select Health Test Metric Set or Default Dashboard Metric Set, or specify metrics by name, metric filtering will be turned off (this is the default behavior).For example, the following configuration enables the collection of metrics required for Health Tests and the jvm_heap_used_mb metric:
  • Include only Health Test Metric Set: Selected.
  • Include/Exclude Custom Metrics: Set to Include.
  • Metric Name: jvm_heap_used_mb
You can also view the JSON representation for this parameter by clicking View as JSON. In this example, the JSON looks like this:{ "includeHealthTestMetricSet": true, "filterType": "whitelist", "metrics": ["jvm_heap_used_mb"] }		 monitoring_metric_filter false

Cgroup CPU Shares Number of CPU shares to assign to this role. The greater the number of shares, the larger the share of the host's CPUs that will be given to this role when the host experiences CPU contention. Must be between 2 and 262144. Defaults to 1024 for processes not managed by Cloudera Manager. cpu.shares 1024 rm_cpu_shares true
Custom Control Group Resources (overrides Cgroup settings) Custom control group resources to assign to this role, which will be enforced by the Linux kernel. These resources should exist on the target hosts, otherwise an error will occur when the process starts. Use the same format as used for arguments to the cgexec command: resource1,resource2:path1 or resource3:path2 For example: 'cpu,memory:my/path blkio:my2/path2' ***These settings override other cgroup settings.*** custom.cgroups rm_custom_resources false
Cgroup I/O Weight Weight for the read I/O requests issued by this role. The greater the weight, the higher the priority of the requests when the host experiences I/O contention. Must be between 100 and 1000. Defaults to 1000 for processes not managed by Cloudera Manager. blkio.weight 500 rm_io_weight true
Cgroup Memory Hard Limit Hard memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' memory.limit_in_bytes -1 MiB rm_memory_hard_limit true
Cgroup Memory Soft Limit Soft memory limit to assign to this role, enforced by the Linux kernel. When the limit is reached, the kernel will reclaim pages charged to the process if and only if the host is facing memory pressure. If reclaiming fails, the kernel may kill the process. Both anonymous as well as page cache pages contribute to the limit. Use a value of -1 to specify no limit. By default processes not managed by Cloudera Manager will have no limit. If the value is -1, Cloudera Manager will not monitor Cgroup memory usage therefore some of the charts will show 'No Data' memory.soft_limit_in_bytes -1 MiB rm_memory_soft_limit true
