Re: hbase heap size
Oleg:
Instead of setting the heap size using the common HBASE_HEAP_SIZE, use
the process specific OPTS to set it.

As Stack says, for instance to set zookeeper specific heap size, you
can uncomment and set the heap size
export HBASE_ZOOKEEPER_OPTS="-Xmx1000m $HBASE_JMX_BASE
-Dcom.sun.management.jmxremote.port=10104"

and so forth instead of HBASE_HEAP_SIZE.
