Hadoop Jobtracker cluster summary of heap size and OOME
Hi,

I'm running a 14 nodes Hadoop cluster with tasktrackers running in all
nodes.

Have set the jobtracker default memory size in hadoop-env.sh

*HADOOP_HEAPSIZE="1024"*
*
*
Have set the mapred.child.java.opts value in mapred-site.xml as,

<property>
  <name>mapred.child.java.opts</name>
<value>-Xmx2048m</value>

Regards,
Viswa.J
