Ted Yu commented on HBASE-20654:
--------------------------------
Several shell commands require region name as parameter. Knowing regions in
transition programmatically gives more choices to shell scripting.
bq. The list exposed here is available via other channels
Please let me know these channels, other than the Web UI.
> Expose regions in transition thru JMX

> URL: https://issues.apache.org/jira/browse/HBASE-20654
> Project: HBase
> Issue Type: Improvement
> Reporter: Ted Yu
> Assignee: liubangchen
> Priority: Major
> Attachments: HBASE-20654-1.patch, HBASE-20654-2.patch
>
>
> Currently only the count of regions in transition is exposed thru JMX.
> Here is a sample snippet of the /jmx output:
> {code}
> {
> "beans" : [ {
> ...
> }, {
> "name" : "Hadoop:service=HBase,name=Master,sub=AssignmentManager",
> "modelerType" : "Master,sub=AssignmentManager",
> "tag.Context" : "master",
> ...
> "ritCount" : 3
> {code}
> It would be desirable to expose region name, state for the regions in
> transition as well.
> We can place configurable upper bound on the number of entries returned in
> case there're a lot of regions in transition.
