stack updated HBASE-4797: ------------------------- Summary: [availability] Skip recovered.edits files with edits we know older than what region currently has (was: [availability] Give recovered.edits files better names, ones that include first and last sequence id so we can skip files with edits we know older than current region has) Updated JIRA subject. > [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.
