Description

Before starting hbase shell i have set some -D parameters reauired for kerberos authentication in HBASE_OPTS (there is no other variables are used when shell is executed). But while invoking Hbase shell it is not used.

The code in hbase-env.sh is
export HBASE_OPTS="-XX:+UseConcMarkSweepGC"

This will overwrite the the value set in the console

There can be 2 options to support this
1. Append the HBASE_OPTS like HBASE_OPTS="$HBASE_OPTS -XX:+UseConcMarkSweepGC".
2. Have a new variable (HBASE_CLIENT_OPTS) which is can be appended in shell section of "hbase" file
