[jira] [Created] (HBASE-13610) Backport HBASE-13222 (Provide means of non-destructive balancer inspection) to 0.98

Andrew Purtell created HBASE-13610:
--------------------------------------

             Summary: Backport HBASE-13222 (Provide means of non-destructive balancer inspection) to 0.98
                 Key: HBASE-13610
                 URL: https://issues.apache.org/jira/browse/HBASE-13610
             Project: HBase
          Issue Type: Task
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell
             Fix For: 0.98.13


We have an internal user who wanted a facility like this during a recent upgrade.
On HBASE-13222 [~elserj] said:
bq.  I've dropped 0.98 from the fixVersions since the patch ended up being much more intrusive than Nicks initial patch.

I skimmed the V3 patch (https://issues.apache.org/jira/secure/attachment/12707615/HBASE-13222-v3.patch) and the essential change is an Admin API addition {{public boolean isBalancerOn()}}, and a new shell command, both of which we can do in 0.98 minors. Going to port back those parts.
