I am facing https://issues.apache.org/jira/browse/WHIRR-146 in 0.7.0
Using CDH
I am debugging an OOME issue with one of the Map tasks.
Here are the opts that I set in receipe
hadoop-mapreduce.mapred.child.java.opts=-Xms5G -Xmx5G
-XX:-HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/mnt/tmp/
-XX:+UseCompressedOops -XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:ErrorFile=/mnt/tmp/java_error%p.log
Here is what the line from the task logs which has failed
<property><!--Loaded from
/data/hadoop/mapred/local/jobTracker/job_201203012345_0004.xml--><name>mapred.child.java.opts</name><value>-Xmx200m</value></property>
the mapred-site.xml has correct entry
<property>
<name>mapred.child.java.opts</name>
<value>-Xms5G -Xmx5G -XX:-HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=/mnt/tmp/ -XX:+UseCompressedOops
-XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75
-XX:ErrorFile=/mnt/tmp/java_error%p.log -XX:PrintGCDateStamps
-XX:+PrintGCDetails -XX:+PrintGCApplicationStoppedTime
-Xloggc:/mnt/tmp/gc_%p.log</value>
</property>
Any suggestions what I might be missing?
thanks
