Duo Zhang resolved HBASE-28457.
-------------------------------
Fix Version/s: 2.6.0
3.0.0-beta-2
2.5.9
Hadoop Flags: Reviewed
Release Note: Introduced a 'version' field in file based tracker record,
so while downgrading, we will know that we are reading a new version of file
tracker file and fail with explicit message instead of failing silently and
causing possible data loss.
Resolution: Fixed
Pushed to branch-2.5+.
Thanks [~wchevreuil] for reviewing!

> Per the discussion around HBASE-27826 and the related design doc, we all
> agree that we should add version field to store file tracker, so when

> file with higher version and fail the initialization, instead of ignore it
> silently and may cause data loss.
