[jira] [Created] (HBASE-25970) MOB data loss - incorrect
concatenation of MOB_FILE_REFS
Peter Somogyi created HBASE-25970:
-------------------------------------
Summary: 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
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.
