Mikhail Antonov commented on HBASE-13904:
-----------------------------------------
When I run this test individually (the method) in idea, I see this NPE when AM
joins the cluster and tries to rebuild user regions (as connection returns null
when asked for meta table). So RunAmJoinCluster thread just dies. (It seems
like this test can't work as of now :) )
When I run the whole class however, all 20 tests in it pass and here's log from
this particular method (let me attach the file).
