'''3. [#3 Can I fix O!utOfMemoryExceptions in hbase?]'''
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).
