Subject [jira] Commented: (HBASE-3329) HLog splitting after RS/cluster death should directly create HFiles
Date Fri, 10 Dec 2010 05:25:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12970073#action_12970073

stack commented on HBASE-3329:
------------------------------

This is fine if one family per region but if ten families per region and 1k regions on the
server, could be a bunch of juggling of files by master process

> After a RS dies or the cluster goes down and we are recovering, we first split HLogs
into the logs for the regions. Then the region servers that host the regions replay the logs
and open the regions.
> This can be made more efficient by directly creating HFiles from the HLogs (instead of
producing a split HLogs file).
