stack commented on HBASE-4797: ------------------------------ bq. The region opening is tried periodically. The waiting interval is about 1/3 of the assignment time out. I think that's fine. >From the log snippet above though Jimmy, it seems like we are updating the >znode every second almost. Thats too much? > [availability] Skip recovered.edits files with edits we know older than what > region currently has > ------------------------------------------------------------------------------------------------- > > Key: HBASE-4797 > URL: https://issues.apache.org/jira/browse/HBASE-4797 > Project: HBase > Issue Type: Bug > Components: performance > Reporter: stack > Assignee: Jimmy Xiang > Priority: Critical > Labels: noob > > Testing 0.92, I crashed all servers out. Another bug makes it so WALs are > not getting cleaned so I had 7000 regions to replay. The distributed split > code did a nice job and cluster came back but interesting is that some hot > regions ended up having loads of recovered.edits files -- tens if not > hundreds -- to replay against the region (can we bulk load recovered.edits > instead of replaying them?). Each recovered.edits file is taking about a > second to process (though only about 30 odd edits per file it seems). The > region is unavailable during this time. -- This message is automatically generated by JIRA.
