Subject [jira] [Updated] (HBASE-13588) ExportSnapshot should checksum data transferred
Date Wed, 29 Apr 2015 17:46:09 GMT

     [ https://issues.apache.org/jira/browse/HBASE-13588?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mubeen Afzal updated HBASE-13588:
---------------------------------
    Description: 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 fail by throwing an IOException.

fail.)
