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 close get the correct sequence id for open. > # Filter all region events from recovered edits > It appears that the close event with a sequence id of one is coming from > region warm up. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
