Subject [jira] [Commented] (HBASE-18357) Enable disabled tests in TestHCM that were disabled by Proc-V2 AM in HBASE-14614
Date Thu, 20 Jul 2017 21:08:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18357?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16095368#comment-16095368

Vladimir Rodionov commented on HBASE-18357:

Three tests fails:

h5. TestClusterStatus

The reason is described above: client connection is not getting periodic ClusterStatus notifications.
This functionality is totally missing in 2.0.
We can leave this test disabled or modify it to remove code which relied on this functionality

h5. TestMulti

Gets deadlocked in Admin.move because test configures RPC_HANDLER_COUNT to be equals to 1.
One handler to Master is taken by test client and when RS tries to report Master Region state
change it is get blocked. 

What we can do is to make all calls from RS to Master are HIGH priority calls or to change
test case and set RPC_HANDLER_COUNT to a default value (one test in test suite relies on vale
of 1 though)

h5. TestRegionCaching

Fixed. Different semantics in 2.0 when call to a region fails due to stale info in a region
cache and there is only one attempt. In pre-2.0 HBase did not do anything, in 2.0 HBase clears
stale cache entry

[~syuanjiang], [~devaraj] what do you think?
