      Description

      If the jobtracker role is defined before the namenode role on the same node (as per majority of the examples), the jobtracker service will poll for namenode and race the namenode HDFS dir config steps, often resulting in a failed write of 'mapred.system.dir' and a dead jobtracker process.
