Elliott Clark ecec35ae4e HBASE-15441 Fix WAL splitting when region has moved multiple times ... Summary: Currently WAL splitting is broken when a region has been opened multiple times in recent minutes. Region open and region close write event markers to the wal. These markers should have the sequence id in them. However it is currently getting 1. That means that if a region has moved multiple times in the last few mins then multiple split log workers will try and create the recovered edits file for sequence id 1. One of the workers will fail and on failing they will delete the recovered edits. Causing all split wal attempts to fail. We need to: It appears that the close event with a sequence id of one is coming from region warm up. This patch fixes that by making sure the close on warm up doesn't happen. Also splitting will ignore any of the events that are already in the logs. Test Plan: Unit tests pass Differential Revision: https://reviews.facebook.net/D55557		2016-03-16 16:26:09 -07:00
