    • Release Note:
      Improved streaming job failure when #link is missing from uri format of -cacheArchive. Earlier it used to fail when launching individual tasks, now it fails during job submission itself.

      Description

      Ran hadoop streaming command as -:
      bin/hadoop jar contrib/streaming/hadoop-*-streaming.jar -input in -output out -mapper "xargs cat" -reducer "bin/cat" -cahceArchive hdfs://h/pathofJarFile
      Streaming submits job to jobtracker and map fails.
      For similar with -cacheFile -:
      bin/hadoop jar contrib/streaming/hadoop-*-streaming.jar -input in -output out -mapper "xargs cat" -reducer "bin/cat" -cahceFile hdfs://h/pathofFile
      followinng error is repoerted back -:
      [
      You need to specify the uris as hdfs://host:port/#linkname,Please specify a different link name for all of your caching URIs
      ]

      Streaming should check about present #link after uri of cacheArchive and should throw proper error .
