Subject [jira] [Commented] (HBASE-19194) TestRSGroupsBase has some always false checks
Date Wed, 08 Nov 2017 00:51:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16243191#comment-16243191
] 

Andrew Purtell commented on HBASE-19194:
----------------------------------------

Without the change in HMaster, the corrected test fails in TestRSGroups#testRegionMove. With
fixed test and change in HMaster, testRegionMove passes.

> Both of these are checks to {{List<T>.contains}} with an element of the wrong type
so they will always return false. The first is an optimization that we can probably live without
(or short circuit on the Master, at least) the second is an assertion that will never fail,
rendering the test ineffective.
