[jira] [Created] (HBASE-22315) Adding some logging which helped us internally in debugging issues

Ankit Singhal created HBASE-22315:
-------------------------------------

             Summary: Adding some logging which helped us internally in debugging issues
                 Key: HBASE-22315
                 URL: https://issues.apache.org/jira/browse/HBASE-22315
             Project: HBase
          Issue Type: Bug
          Components: logging
    Affects Versions: 2.2.0
            Reporter: Ankit Singhal


[~ted_yu]/[~elserj] has added some logging to debug certain cases(defined below) encountered during the testing.

 

* Region replica ends up on the same RS - add debug log for RegionReplicaHostCostFunction
* Debugging why regionservers are going down with Memstore compaction
* When hbase:namespace table was not assigned
* Logging in Procedure wals to debug HBASE-20552
* HMaster not assigning regions properly with RSGroups feature

 

Currently, it is sitting in our local branch but it would be good if we can add them upstream so others can also benefit from it.
