--------------------------------------

             Summary: Detect and fix corrupted local index region during compaction
                 Key: PHOENIX-3609
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3609
             Project: Phoenix
          Issue Type: Bug
            Reporter: Ankit Singhal
            Assignee: Ankit Singhal


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.
