Subject [jira] [Commented] (HBASE-5325) Expose basic information about the master-status through jmx beans

Hitesh Shah commented on HBASE-5325:
------------------------------------

@Stack, thanks for the review comments. Couple of clarifications/questions: 

bq. Does this need to be public? Can it be protected in AM?
  - This was added to RegionState to expose the private field ServerName for display with
regions in transition.
  - Noticed that it can be null so will make a minor mod to handle the null case. 

bq. Please file an issue to move +import org.apache.hadoop.metrics.util.MBeanUtil; to o.a.h.h.u
  - Didn't understand this - could you clarify as MBeanUtil is part of hadoop-core? 

bq. maybe o.a.hbase instead of o.a.h.h
  - Will change. 

bq. isMasterActive 
  - will add. 

bq. Do you think this Interface belongs in Metrics? Why not call it RegionServerMXBeanImpl.java
or just MXBeanImpl
  - will move the interfaces to master and regionserver respectively. 
  - will change to call them MXBean and MXBeanImpl in both master and regionserver as the
package names already denote what kind of object the bean represents. 

bq. Do you have to do this getHBaseMaster with all of the messing to construct a master name
  - Will replace with the zk quorum info if that seems appropriate.

> Similar to the Namenode and Jobtracker, it would be good if the hbase master could expose
some information through mbeans.
