Thanks a lot. > Implement a distributed MOB compaction by procedure > --------------------------------------------------- > > Key: HBASE-15381 > URL: https://issues.apache.org/jira/browse/HBASE-15381 > Project: HBase > Issue Type: Improvement > Components: mob > Reporter: Jingcheng Du > Assignee: Jingcheng Du > Attachments: HBASE-15381-v2.patch, HBASE-15381.patch, mob distributed compaction design-v2.pdf, mob distributed compaction design.pdf > > > In MOB, there is a periodical compaction which runs in HMaster (It can be disabled by configuration), some small mob files are merged into bigger ones. Now the compaction only runs in HMaster which is not efficient and might impact the running of HMaster. In this JIRA, a distributed MOB compaction is introduced, it is triggered by HMaster, but all the compaction jobs are distributed to HRegionServers. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
