      Description

      In particular, this can be reproduced in Windows by running a hadoop example such as PiEstimator.

      org.apache.hadoop.util.DiskChecker$DiskErrorException: Could not find taskTracker/pids/attempt_200902021632_0001_m_000002_0 in any of the configured local directories
      	at org.apache.hadoop.fs.LocalDirAllocator$AllocatorPerContext.getLocalPathToRead(LocalDirAllocator.java:381)
      	at org.apache.hadoop.fs.LocalDirAllocator.getLocalPathToRead(LocalDirAllocator.java:138)
      	at org.apache.hadoop.mapred.TaskTracker.getPidFilePath(TaskTracker.java:430)
      	at org.apache.hadoop.mapred.TaskTracker.removePidFile(TaskTracker.java:440)
      	at org.apache.hadoop.mapred.JvmManager$JvmManagerForType$JvmRunner.runChild(JvmManager.java:370)
      	at org.apache.hadoop.mapred.JvmManager$JvmManagerForType$JvmRunner.run(JvmManager.java:338)
      

      (Have changed TaskTracker.java to print out the trace.)

      This patch disables usage of setsid and pidfiles on Windows.
