Matteo Bertozzi commented on HBASE-4391:
----------------------------------------
{code}
$ mvn package -DskipTests -Pnative
$ ls ./hbase-server/target/native/libmlockall_agent.so
{code}
or if you use assembly:assembly
in ./target/hbase-0.95-SNAPSHOT.tar.gz
under hbase-0.95-SNAPSHOT/native folder there's the libmlockall_agent.so
> Add ability to start RS as root and call mlockall

> A common issue we've seen in practice is that users oversubscribe their
> region servers with too many MR tasks, etc. As soon as the machine starts
> swapping, the RS grinds to a halt, loses ZK session, aborts, etc.
> This can be combatted by starting the RS as root, calling mlockall(), and
> then setuid down to the hbase user. We should not require this, but we should
> provide it as an option.
