Vladimir Rodionov commented on HBASE-22075: ------------------------------------------- {quote} What is creating multiple files? {quote} Forced splits during bulkload due to changed region boundaries, [~elserj]. > Potential data loss when MOB compaction fails > --------------------------------------------- > > Key: HBASE-22075 > URL: https://issues.apache.org/jira/browse/HBASE-22075 > Project: HBase > Issue Type: Bug > Components: mob > Affects Versions: 2.1.0, 2.0.0, 2.0.1, 2.1.1, 2.0.2, 2.0.3, 2.1.2, 2.0.4, > 2.1.3 > Reporter: Vladimir Rodionov > Assignee: Vladimir Rodionov > Priority: Critical > Labels: mob > Fix For: 2.2.0, 2.0.5, 2.1.4 > > Attachments: HBASE-22075-v1.patch > > > When MOB compaction fails during last step (bulk load of a newly created > reference file) there is a high chance of a data loss due to partially loaded > reference file, cells of which refer to (now) non-existent MOB file. The > newly created MOB file is deleted automatically in case of a MOB compaction > failure, but some cells with the references to this file might be loaded to > HBase. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
