Ankit Singhal updated PHOENIX-3609:
-----------------------------------
Attachment: BUG-67084_v1.patch
[[email protected]], can you please review the attached patch.
-- Current check is just to check the prefix of store file's first row key with
region start key and rebuild the region using data table store files.
-- It can give a false negative in some cases, where the data is in such a way
that prefix can match. those cases are not yet handled. I may check IndexId and
see if it is less than the highest indexId.
> Detect and fix corrupted local index region during compaction

> Local index regions can be corrupted when hbck is run to fix the overlap
> regions and directories are simply merged for them to create a single region.
> we can detect this during compaction by looking at the start keys of each
> store files and comparing prefix with region start key. if local index for
> the region is found inconsistent, we will read the store files of
> corresponding data region and recreate a data.
