Re: java.lang.OutOfMemoryError: Java heap space

Thats a lot of regions per regionserver.  You should up the size of
your regions if they are default sized.  But look in your regionserver
UI.  That'll tell you a better story regards how much of your heap is
given over to keeping storefile indices in memory.  Can you give hbase
more than this 4G?
