If #link is missing from uri format of -cacheArchive then streaming does not throw error.

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 .
