[jira] [Updated] (MAPREDUCE-2545) [Rumen] Rumen incorrectly emits
memory usages of map/reduce tasks
[ https://issues.apache.org/jira/browse/MAPREDUCE-2545?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Allen Wittenauer updated MAPREDUCE-2545:
----------------------------------------
Fix Version/s: (was: 0.24.0)
> [Rumen] Rumen incorrectly emits memory usages of map/reduce tasks
> -----------------------------------------------------------------
>
> Key: MAPREDUCE-2545
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2545
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tools/rumen
> Reporter: Amar Kamat
>
> Rumen emits job and task (map/reduce) level heap settings (i.e values of mapred.child.java.opts, mapreduce.map.java.opts and mapreduce.reduce.java.opts). It also emits cluster and task (map/reduce) level memory configurations (e.g mapreduce.cluster.mapmemory.mb, mapreduce.cluster.reducememory.mb, mapreduce.map.memory.mb and mapreduce.reduce.memory.mb). Currently, it incorrectly sets map/reduce task level memory usage to the max heap values obtained from mapreduce.map.java.opts and mapreduce.reduce.java.opts. Note that HadoopLogsAnalyzer correctly sets it.
> Also the cluster level task level (map/reduce) memory configurations are missing.
