[jira] [Commented] (HBASE-21235) Rename the closed procedure wal files so that we do not need to call recoverLease when restarting

    [ https://issues.apache.org/jira/browse/HBASE-21235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16630120#comment-16630120 ] 

Duo Zhang commented on HBASE-21235:
-----------------------------------

It is not easy as I expected... We have a ProcedureWALFile and the file name is stored in this class, and we will use this class to archive the old log files. So when renaming we also need to change the file name in this class and it may introduce races...

Maybe a once for all solution is to just get rid of the current wal based procedure store. Just use a HRegion...

Will be back later...

> If there are lots of procedure wal files the recover lease will be a time consuming operation. Renaming is a possible way to confirm that some files are already closed when restarting so we do not need to call recoverLease on them any more.
