[jira] [Created] (HBASE-11325) Malformed RPC calls can corrupt stores

Esteban Gutierrez created HBASE-11325:
-----------------------------------------

             Summary: Malformed RPC calls can corrupt stores
                 Key: HBASE-11325
                 URL: https://issues.apache.org/jira/browse/HBASE-11325
             Project: HBase
          Issue Type: Bug
          Components: Client, regionserver
    Affects Versions: 0.94.20
            Reporter: Esteban Gutierrez


We noticed in a cluster a Region Server that aborted with a DroppedSnapshotException due an IOException in ScanWildcardColumnTracker when the RS tried to flush the memstore. After further research it was found that a client was sending corrupt RPCs requests to the RS and those corrupt requests ended into the stores causing corruption of the memstore itself and in some cases HFiles.  More details to follow.
