Anoop Sam John commented on HBASE-15381: ---------------------------------------- Ya we need this very much.. Doing all MOB compaction IO within single process HM is not good. +1 for the task. > 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 > > 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)
