[jira] [Commented] (HBASE-4348) Add metrics for regions in
transition
[ https://issues.apache.org/jira/browse/HBASE-4348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13215769#comment-13215769 ]
Himanshu Vashishtha commented on HBASE-4348:
--------------------------------------------
I have created a patch, which involves a new method in org.apache.hadoop.hbase.master.AssignmentManager and supporting code in src/main/jamon/org/apache/hbase/tmpl/master/AssignmentManagerStatusTmpl.jamon.
I am running it on my local system, and wonder about how to test this, i.e., to get some regions in RIT. Any suggestions please?
