[jira] [Created] (HBASE-13588) ExportSnapshot should checksum data transferred

Mubeen Afzal created HBASE-13588:
------------------------------------

             Summary: ExportSnapshot should checksum data transferred
                 Key: HBASE-13588
                 URL: https://issues.apache.org/jira/browse/HBASE-13588
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.0.1, 2.0.0, 0.98.13
            Reporter: Mubeen Afzal
            Assignee: Mubeen Afzal


We sent quite a bit of data using ExportSnapshot and noticed some corruption.  We use checksums to verify if we have transferred a particular file but never do any verification after the file has been transferred.  I propose that we do a checksum upon completing file transfer and if the checksums do not match up, I propose we retry x number of times and then fails.
