------------------------------------
Summary: Data loss in MOB files after cloning a snapshot and
deleting that snapshot
Key: HBASE-16841
URL: https://issues.apache.org/jira/browse/HBASE-16841
Project: HBase
Issue Type: Bug
Components: mob, snapshots
Reporter: Jingcheng Du
Assignee: Jingcheng Du
When taking a snapshot on a enabled mob table, a region flushes itself and
takes a snapshot, and the mob snapshot is taken if it is first region of the
table. At that time, the flushing of some regions might not be finished, and
some mob files are not flushed to disk yet. Eventually some mob files are not
existent in the snapshot manifest.
We need to have a mob manifest for each region server after the snapshot of all
online regions in that server are finished, and merge them in master when all
the snapshots of regions are finished at last.
