Esteban Gutierrez commented on HBASE-14354:
-------------------------------------------
Also the latest change verifies if $HBASE_REGIONSERVER is equal to $USER if
both are the same then just ignore the user name option, otherwise use the
provided $HBASE_REGIONSERVER_UID
> Minor improvements for usage of the mlock agent

> 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)
