Nick Dimiduk updated HBASE-10518:
---------------------------------

    Attachment: HBASE-10518.00.patch

This hasn't to do with the lack of configuration, it's (probably) the JVM 
lacking the "MemoryUsed" attribute on the direct BufferPool bean. What JDK are 
you using?

Give this patch a try. It'll log only once and also include the stacktrace 
instead of swallowing it.

> DirectMemoryUtils.getDirectMemoryUsage spams when none is configured

> My logs are full of "Failed to retrieve nio.BufferPool direct MemoryUsed". 
> Even if it's DEBUG, it adds no value. It'd just remove.
