      Description

      Here is the exception:

      2014-08-20 01:14:36,594 ERROR executor.Executor (Logging.scala:logError(96)) - Exception in task 0.0 in stage 1.0 (TID 0)

      Basically, the cause is that RowContainer is misused(it's not allowed to write once someone read row from it), i'm trying to figure out whether it's a hive issue or just in hive on spark mode.
