Vladimir Rodionov commented on HBASE-17852: ------------------------------------------- Some notes after initial analysis of implementation of bulk-loaded files support # RegionObserver coprocessor has pre-commit and post-commit code (kind of Tx), but only on a region level. No Tx support on a table level. This means that if (for some regions), loading files fail, we will be left with a partial data in both: table store physical location and in backup system table. What we need here is Tx support for the whole bulk load operation cluster-wide (prepare, commit). And hooks exposed for custom coprocessor (Master?). # What will happen if bulk load operation runs at the same time as incremental backup? Backup will see partial updates, but it should not. # We add files to backup system tables, but I have not found where and when we deleted those files. > Add Fault tolerance to HBASE-14417 (Support bulk loaded files in incremental > backup) > ------------------------------------------------------------------------------------ > > Key: HBASE-17852 > URL: https://issues.apache.org/jira/browse/HBASE-17852 > Project: HBase > Issue Type: Sub-task > Reporter: Vladimir Rodionov > Assignee: Vladimir Rodionov > Fix For: 2.0.0 > > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
