> MOB data loss - incorrect concatenation of MOB_FILE_REFS
> ---------------------------------------------------------
>
> Key: HBASE-25970
> URL: https://issues.apache.org/jira/browse/HBASE-25970
> Project: HBase
> Issue Type: Bug
> Components: mob
> Affects Versions: 3.0.0-alpha-1
> Reporter: Peter Somogyi
> Assignee: Peter Somogyi
> Priority: Critical
> Fix For: 3.0.0-alpha-1
>
>
> Active MOB files can be deleted by MobFileCleanerChore. The MOB_FILE_REFS are
> wrongly concatenated when multiple files or tables are stored. During the MOB
> cleanup HBase wants to keep the incorrectly concatenated file and considers
> the real file as deletable.
