             Summary: Region data ended up in a file of an another region
                 Key: HBASE-18098
                 URL: https://issues.apache.org/jira/browse/HBASE-18098
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.2.0
            Reporter: Pavel Salimov


Somehow it happened that a region, say AB, was split onto A and B, but some portion of B's data were missing in B's H-files, still presenting in A's files. I am not completely sure, was it a result of just a failure during split, or of applying hbck repair after that. 

Anyway, data of some rows belonging to B were missing accessing normally. I was able to access them making a scan type query regarding these rows to region A (despite the rows are after its end). Hbck repairs, splitting A onto A0, A1 and (full) compaction did not change the situation: the data were still missing in B migrated to A1. 
 
I am reporting the issue in hope to get an advice on how to detect such an inconsistency as well as hoping to clarify what leaded to such a state (and fixed if it is a bug).
