[jira] [Commented] (HBASE-7475)
TestUpgradeFromHFileV1ToEncoding.testUpgrade hangs
[ https://issues.apache.org/jira/browse/HBASE-7475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13542305#comment-13542305 ]
nkeywal commented on HBASE-7475:
--------------------------------
Hum. In a way, it's simple. We're doing a region split, and it seems that the test doesn't think we will split.
In another, may be there is a real bug behind this. I'm not sure: but basically the regionserver will not stop until the split is finished. To finish it needs meta. And I guess meta is not there anymore as we're closing.
May be we should not stop the regionserver holding meta if a split is in progress?
Let see first if disabling the split helps.
