Jonathan Hsieh commented on HBASE-11644: ---------------------------------------- I reorganized the description to make it easier to follow. > External MOB compaction tools > ----------------------------- > > Key: HBASE-11644 > URL: https://issues.apache.org/jira/browse/HBASE-11644 > Project: HBase > Issue Type: Sub-task > Components: Compaction, master > Reporter: Jingcheng Du > Assignee: Jingcheng Du > > The MOB files are involved in the HBase compaction. It means there's no > chance to delete and merge the MOB files. The external tools do this, one is > a cleaner to clean the MOB files that are expired (by TTL and minVersions), > the other one is a sweep tool to clean the deleted Cells in HBase and merge > small files into bigger ones. These tools are triggered by users. Besides, > the cleaner could be a chore in HMaster. -- This message was sent by Atlassian JIRA (v6.2#6252)
