I/O Sort Factor	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. This determines the number of open file handles. Merging more files in parallel reduces merge sort iterations and improves run time by eliminating disk I/O. 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.

I/O Sort Memory Buffer (MiB)	The total amount of memory buffer, in megabytes, to use while sorting files. Note that this memory comes out of the user JVM heap size (meaning total user JVM heap - this amount of memory = total user usable heap space. Note that Cloudera's default differs from Hadoop's default; Cloudera uses a bigger buffer by default because modern machines often have more RAM. The smallest value across all TaskTrackers will be part of generated client configuration.	mapreduce.task.io.sort.mb	256 MiB	io_sort_mb	false
I/O Sort Spill Percent	The soft limit in either the buffer or record collection buffers. When this limit is reached, a thread will begin to spill the contents to disk in the background.

Default Number of Parallel Transfers During Shuffle	The default number of parallel transfers run by reduce during the copy (shuffle) phase. This number is calculated by the following formula: min(number_of_nodes, n * min(number_of_cores_per_node, number_of_spindles_per_node)) where the n represents how many streams you want to run per core/spindle. A value of 10 for n is appropriate in most cases. Will be part of generated client configuration.	mapreduce.reduce.shuffle.parallelcopies	10	mapred_reduce_parallel_copies	false

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 than rate 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 publish rate events or fewer. If not specified, the default is one minute threshold - 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. Example: {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, 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.		version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated.

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 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 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 configured for a DataNode 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"}]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.

Rules to Extract Events from Log Files	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 than rate 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 publish rate events or fewer. If not specified, the default is one minute threshold - 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. Example: {"alert": false, "rate": 10, "exceptiontype": "java.lang.StringIndexOutOfBoundsException"}This rule sends events to Cloudera Manager for every StringIndexOutOfBoundsException, 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.		version: 0, rules: [ alert: false, rate: 1, periodminutes: 1, threshold: FATAL , alert: false, rate: 0, threshold: WARN, content: .* is deprecated. Instead, use .* , alert: false, rate: 0, threshold: WARN, content: .* is deprecated.

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 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 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 configured for a DataNode 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"}]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.
