Java Configuration Options for Lily HBase Indexer These arguments will be passed as part of the Java command line. Commonly, garbage collection flags or extra debugging flags would be passed here. -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:-CMSConcurrentMTEnabled -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled hbase_indexer_java_opts false

Lily HBase Indexer Logging Advanced Configuration Snippet (Safety Valve) For advanced use only, a string to be inserted into log4j.properties for this role only. log4j_safety_valve 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 doesn't exist. However, if this directory already exists, role user must have write access to this directory. If this directory is shared amongst multiple roles, it should have 1777 permissions. Note that 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. /tmp oom_heap_dump_dir false
Dump Heap When Out of Memory When set, generates heap dump file when java.lang.OutOfMemoryError is thrown. false oom_heap_dump_enabled true
Kill When Out of Memory When set, a SIGKILL signal is sent to the role process when java.lang.OutOfMemoryError is thrown. true oom_sigkill_enabled true
Automatically Restart Process When set, this role's process is automatically (and transparently) restarted in the event of an unexpected failure. false process_auto_restart true

Monitoring

Display Name Description Related Name Default Value API Name Required
Enable Health Alerts for this Role When set, Cloudera Manager will send alerts when the health of this role reaches the threshold specified by the EventServer setting eventserver_health_events_alert_threshold true enable_alerts false
Enable Configuration Change Alerts When set, Cloudera Manager will send alerts when this entity's configuration changes. false enable_config_alerts false
File Descriptor Monitoring Thresholds The health test thresholds of the number of file descriptors used. Specified as a percentage of file descriptor limit. Warning: 50.0 %, Critical: 70.0 % hbase_indexer_fd_thresholds false
Lily HBase Indexer Host Health Test When computing the overall Lily HBase Indexer health, consider the host's health. true hbase_indexer_host_health_enabled false
Lily HBase Indexer Process Health Test Enables the health test that the Lily HBase Indexer's process state is consistent with the role configuration true hbase_indexer_scm_health_enabled false
Log Directory Free Space Monitoring Absolute Thresholds The health test thresholds for monitoring of free space on the filesystem that contains this role's log directory. Warning: 10 GiB, Critical: 5 GiB log_directory_free_space_absolute_thresholds false
Log Directory Free Space Monitoring Percentage Thresholds The health test thresholds for monitoring of free space on the filesystem that contains this role's log directory. Specified as a percentage of the capacity on that filesystem. This setting is not used if a Log Directory Free Space Monitoring Absolute Thresholds setting is configured. Warning: Never, Critical: Never log_directory_free_space_percentage_thresholds false
Role Triggers The configured triggers for this role. 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 all of the following fields:
  • triggerName (mandatory) - the name of the trigger. This value must be unique for the specific role.
  • 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 will cause the condition to fire.
  • enabled (optional) - by default set to 'true'. If set to 'false' the trigger will not be evaluated.
For example, here is a JSON formatted trigger configured for a DataNode that fires if the DataNode has more than 1500 file-descriptors opened:
[{"triggerName": "sample-trigger",
  "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad",
  "streamThreshold": 0, "enabled": "true"}]
Consult the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change in the future and as a result backward compatibility is not guaranteed between releases at this time.		 [] role_triggers true
Unexpected Exits Thresholds The health test thresholds for unexpected exits encountered within a recent period specified by the unexpected_exits_window configuration for the role. Warning: Never, Critical: Any unexpected_exits_thresholds false
Unexpected Exits Monitoring Period The period to review when computing unexpected exits. 5 minute(s) unexpected_exits_window false

Resource Management

Display Name Description Related Name Default Value API Name Required
Java Heap Size of Lily HBase Indexer in Bytes Maximum size in bytes for the Java Process heap memory. Passed to Java -Xmx. 1 GiB hbase_indexer_java_heapsize 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
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 B to specify no limit. By default processes not managed by Cloudera Manager will have no limit. 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 B to specify no limit. By default processes not managed by Cloudera Manager will have no limit. memory.soft_limit_in_bytes -1 MiB rm_memory_soft_limit true

Healthy Lily HBase Indexer Monitoring Thresholds The health test thresholds of the overall Lily HBase Indexer health. The check returns "Concerning" health if the percentage of "Healthy" Lily HBase Indexers falls below the warning threshold. The check is unhealthy if the total percentage of "Healthy" and "Concerning" Lily HBase Indexers falls below the critical threshold. Warning: 95.0 %, Critical: 90.0 % ks_indexer_indexers_healthy_thresholds 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 all of 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 will cause the condition to fire.
  • enabled (optional) - by default set to 'true'. If set to 'false' the trigger will not be evaluated.
For example, here is a JSON formatted trigger that 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"}]
