> 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:p/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:p/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 .
