Description

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.
