Summary: Fix WAL splitting when region has moved multiple times
Key: HBASE-15441
URL: https://issues.apache.org/jira/browse/HBASE-15441
Project: HBase
Issue Type: Bug
Reporter: Elliott Clark
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:
# make sure that open and close get the correct sequence id for open.
# Filter all region events from recovered edits
