[jira] Updated: (HBASE-3419) If re-transition to OPENING during log
replay fails, server aborts. Instead, should just cancel region open.
[ https://issues.apache.org/jira/browse/HBASE-3419?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Gray updated HBASE-3419:
---------------------------------
Attachment: HBASE-3419-v1.patch
As outlined.
Had to add new {{CancelableProgressable}} interface because we needed to be able to tell the caller to cancel the operation.

> The {{Progressable}} used on region open to tickle the ZK OPENING node to prevent the master from timing out a region open operation will currently abort the RegionServer if this fails for some reason. However it could be "normal" for an RS to have a region open operation aborted by the master, so should just handle as it does other places by reverting the open.
> We had a cluster trip over some other issue (for some reason, the tickle was not happening in < 30 seconds, so master was timing out every time). Because of the abort on BadVersion, this eventually led to every single RS aborting itself eventually taking down the cluster.
