      Description

      I'm occasionally (1/5000 times) getting this error after upgrading everything to hadoop-0.18:

      08/09/09 03:28:36 INFO dfs.DFSClient: Exception in createBlockOutputStream java.io.IOException: Could not read from stream
      08/09/09 03:28:36 INFO dfs.DFSClient: Abandoning block blk_624229997631234952_8205908

      DFSClient contains the logging code:

      LOG.info("Exception in createBlockOutputStream " + ie);

      This would be better written with ie as the second argument to LOG.info, so that the stack trace could be preserved. As it is, I don't know how to start debugging.
