Map/Reduce jobs with small value sizes fail because of timeouts putting intermediate keys into the cache

    Details

      Description

      The following exception occurs on the primary node running a Map/Reduce job with 1KB values:

      ISPN-2836 added a timeout for the entire MapReduceTask, but this timeout is happening when the intermediate keys are put into the cache by the map phase. This error does not occur when the value size is 8KB or larger.
