+ 
  Out-of-the-box, hbase uses the default JVM heap size.  Set the ''HBASE_HEAPSIZE'' \
environment variable in ''${HBASE_HOME}/conf/hbase-env.sh'' if your install needs to \
run with a larger heap.  ''HBASE_HEAPSIZE'' is like ''HADOOP_HEAPSIZE'' in that its \
value is the desired heap size in MB.  The surrounding '-Xmx' and 'm' needed to make \
up the maximum heap size java option are added by the hbase start script (See how \
''HBASE_HEAPSIZE'' is used in the ''${HBASE_HOME}/bin/hbase'' script for \
clarification).
