sam liu commented on MAPREDUCE-6204: ------------------------------------ In Hadoop 2.x, the property JobConf.MAPRED_TASK_JAVA_OPTS is deprecated, and hadoop will ignore this property directly without replacing its new values(MAPRED_MAP_TASK_JAVA_OPTS and MAPRED_REDUCE_TASK_JAVA_OPTS). This issue will cause test TestJobCounters fail on PPC64 platform sometimes, as PPC64 JVM sometimes comsumes more memory when executing map/reduce tasks and might encounter JVM crashing issue once the default heap size is exhausted. > TestJobCounters should use new properties instead > JobConf.MAPRED_TASK_JAVA_OPTS > ------------------------------------------------------------------------------- > > Key: MAPREDUCE-6204 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6204 > Project: Hadoop Map/Reduce > Issue Type: Test > Components: test > Affects Versions: 2.6.0 > Reporter: sam liu > Assignee: sam liu > Priority: Minor > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
