[jira] [Resolved] (HBASE-7751) TestDelayedRpc occasionally fails in
trunk
[ https://issues.apache.org/jira/browse/HBASE-7751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stack resolved HBASE-7751.
--------------------------
Resolution: Not A Problem
Resolving as 'not a problem'. No patch applied. I went over the last twenty builds on EC2 and this test is not mentioned. Looked at last ten on apache builds and no failure of this test. Lets open new issue if we see it again and some diagnosis of what is up has gone on.
