[jira] [Created] (HBASE-20044) TestClientClusterStatus is flakey
stack created HBASE-20044:
-----------------------------
Summary: TestClientClusterStatus is flakey
Key: HBASE-20044
URL: https://issues.apache.org/jira/browse/HBASE-20044
Project: HBase
Issue Type: Sub-task
Components: flakey
Reporter: stack
It killed a nightly. Failed in flakey suite. The compare is too sensitive to slightest variance. Here are two failiures... one because the previous test had not finished putting back a Region that had been offlined, and the other because the count of requests was off slightly. Let me make the compare coarser....
