[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
Fix For: 0.23.0
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.
