      Description

      If I compile pipes examples on branch 1:

      ant -Dcompile.c++=yes examples
      

      And then try to run it on an MR2 cluster, the pipes job hangs forever at map 0% reduce 0%, I can see in the maps stderr:

      Hadoop Pipes Exception: Illegal text protocol command 
      

      The issue here is that if users have older pipes job, they won't be able to run it on MR2 (without recompilation). Is this expected or there is something to be fixed so jobs can be used interchangeably? Or should we document it as an incompatibility?

        It is expected to require recompilation if not outright code changes on major version upgrades. This is documented in the Hadoop Compatibility Guide.

        Closing as won't fix.
