I/O Sort Factor
- Description
- The number of streams to merge at the same time while sorting files. That is, the number of sort heads to use during the merge sort on the reducer side.

Note that merging more files in parallel uses more memory. If 'io.sort.factor' is set too high or the maximum JVM heap is set too low, excessive garbage collection will occur. The Hadoop default is 10, but Cloudera recommends a higher value. Will be part of generated client configuration.

Rules to Extract Events from Log Files
- Description
- This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
alert
- whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".rate
(mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more thanrate
matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.periodminutes
- the number of minutes during which the publisher will only publishrate
events or fewer. If not specified, the default is one minutethreshold
- apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.content
- match only those messages for which contents match this regular expression.exceptiontype
- match only those messages that are part of an exception message. The exception type must match this regular expression.
{"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}
This rule sends events to Cloudera Manager for everyStringIndexOutOfBoundsException
, up to a maximum of 10 every minute.{"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}
In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.

Rules to Extract Events from Log Files
- Description
- This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
alert
- whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".rate
(mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more thanrate
matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.periodminutes
- the number of minutes during which the publisher will only publishrate
events or fewer. If not specified, the default is one minutethreshold
- apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.content
- match only those messages for which contents match this regular expression.exceptiontype
- match only those messages that are part of an exception message. The exception type must match this regular expression.
{"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}
This rule sends events to Cloudera Manager for everyStringIndexOutOfBoundsException
, up to a maximum of 10 every minute.{"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}
In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
- Related Name
- Default Value
- version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 0, threshold: WARN, content: .* is deprecated.

Cgroup Memory Hard Limit
- Description
- 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'

Strict CGroup Resource Usage
- Description
- CGroups allows cpu usage limits to be hard or soft. When this setting is true, containers cannot use more CPU usage than allocated even if spare CPU is available. This ensures that containers can only use CPU that they were allocated. When set to false, containers can use spare CPU if available. It should be noted that irrespective of whether set to true or false, at no time can the combined CPU usage of all containers exceed the value specified in Containers CPU Limit Percentage.

Rules to Extract Events from Log Files
- Description
- This file contains the rules that govern how log messages are turned into events by the custom log4j appender that this role loads. It is in JSON format, and is composed of a list of rules. Every log message is evaluated against each of these rules in turn to decide whether or not to send an event for that message. If a log message matches multiple rules, the first matching rule is used.. Each rule has some or all of the following fields:
alert
- whether or not events generated from this rule should be promoted to alerts. A value of "true" will cause alerts to be generated. If not specified, the default is "false".rate
(mandatory) - the maximum number of log messages matching this rule that can be sent as events every minute. If more thanrate
matching log messages are received in a single minute, the extra messages are ignored. If rate is less than 0, the number of messages per minute is unlimited.periodminutes
- the number of minutes during which the publisher will only publishrate
events or fewer. If not specified, the default is one minutethreshold
- apply this rule only to messages with this log4j severity level or above. An example is "WARN" for warning level messages or higher.content
- match only those messages for which contents match this regular expression.exceptiontype
- match only those messages that are part of an exception message. The exception type must match this regular expression.
{"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}
This rule sends events to Cloudera Manager for everyStringIndexOutOfBoundsException
, up to a maximum of 10 every minute.{"alert": false, "rate": 1, "periodminutes": 1, "exceptiontype": ".*"}, {"alert": true, "rate": 1, "periodminutes": 1, "threshold":"ERROR"}
In this example, an event generated may not be promoted to alert if an exception is in the ERROR log message, because the first rule with alert = false will match.
- Related Name
- Default Value
