Íñigo Goiri commented on HDFS-15245:
------------------------------------
For completion, I would add javadocs to the new methods in JournalNodeMXBean.
In particular the description for getClusterIds() should add the explanation
about supporting multiple clusters.
Other than that, this is good to go.
