Subject [jira] [Commented] (HBASE-7431) TestSplitTransactionOnCluster tests still flaky
Date Mon, 24 Dec 2012 00:24:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13539132#comment-13539132
] 

Lars Hofhansl commented on HBASE-7431:
--------------------------------------

This test also starts *way* to many region servers.
HBaseTestingUtil.ensureSomeNonStoppedRegionServersAvailable is wrong. For each stopped/stopping
RegionServer is starts a new one. As RSs are started/stopped there will be many that are just
stopping, and this method will create way more running RSs than requested.

> I still see occasional failures:
> # Assuming all regions of a table are only, even when a previous may have shut down one
of the RSs, in which case it might take some for these regions to be online again.
> # Assuming propagation from ZK to RS is instant, even though communication to watchers
is asynchronous
