Subject [jira] [Commented] (HBASE-9338) Test Big Linked List fails on Hadoop 2.1.0
Date Mon, 09 Sep 2013 22:42:56 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13762412#comment-13762412

Jeffrey Zhong commented on HBASE-9338:

[~eclark] In the SlowDeterministic mode, we have several places doing region move such as
MoveRandomRegionOfTableAction and MoveRegionsOfTableAction. In the region assignment code,
if we try to move a region from a dead server(or a region is being closed and HMaster retry
the unassign), the region will be offlined and we'll lose the region(because it won't be re-assigned
to any region server anymore). I think it's better to disable region move(and balancer as
well) in the tests to isolate if the data loss is caused by region movement combining with
other factors.
