-----------------------------------------

             Summary: Minor improvements for usage of the mlock agent
                 Key: HBASE-14354
                 URL: https://issues.apache.org/jira/browse/HBASE-14354
             Project: HBase
          Issue Type: Bug
          Components: hbase, regionserver
            Reporter: Esteban Gutierrez
            Priority: Trivial


1. MLOCK_AGENT points to the wrong path in hbase-config.sh

When the mlock agent is build, the binary is installed under $HBASE_HOME/lib/native  and not
under $HBASE_HOME/native

2. By default we pass $HBASE_REGIONSERVER_UID to the agent options which causes the mlock
agent to attempt to do a setuid in order to mlock the memory of the RS process. We should
only pass that user if specified in the environment, not by default. (the agent currently
handles that gracefully)
