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>

Hi Arun,

Will not cross post hereafter.

I had the same heap size value, same no.of jobs,scheduler and it is works
fine in hadoop 1.0.4 version for 8 to 9 months, but I'm facing this JT OOME
issue in hadoop 1.2.1 version only.

Even though I tried to set heap size max of 16G but it eats the whole
memory.

HADOOP_HEAPSIZE of 1024 is too low. You might want to bump it up to 16G or more, depending on:
* #jobs
* Scheduler you use.
