Hi Avani,
  4 gigs might be enough for your app.. But did you make sure that you are using a 64-bit
jvm?

Well, I have a 16G machine and I do not want to give all memory to hbase since each hbase
deamon will take 4Gigs - master and regionserver are running  on the same machines and also
hdfs daemons.

Make sure you are using a 64 bit JVM as opposed to 32-bit.. 32 bit java doesn't allow more
than 3-4 gigs..

Giving 4G to HBASE_HEAPSIZE fails to start the JVM.

Thanks,
