Description

History server was started with -Xmx10000m
Ran GridMix V3 with 1200 Jobs trace in STRESS mode on 350 nodes with each node 4 NMS.
All jobs finished as reported by RM Web UI and HADOOP_MAPRED_HOME/bin/mapred job -list all
But found that GridMix job client was stuck while trying connect to HistoryServer
Then tried to do HADOOP_MAPRED_HOME/bin/mapred job -status jobid
JobClient also got stuck while looking for token to connect to History server
Then looked at History Server logs and found History is trowing "java.lang.OutOfMemoryError: GC overhead limit exceeded" error.

With 10GB of Heap space and 1200 Jobs, History Server should not go out of memory .
No matter what are the type of jobs.
