    • Release Note:
      Changed connection protocol job tracker and task tracker so that task tracker will not connect to a job tracker with a different build version.

      Description

      After one mapred system upgrade, we noticed that all tasks assigned to one task tracker failed. It turned out that for some reason the task tracker was not upgraded.

      To avoid this, a task tracker should reports its version # when it registers itsself with a job tracker. If the job tracker receives an inconsistent version #, it should refuse the connection.
