Hadoop streaming in sandbox

  • #29404
    Duncan Gunn


    I was wondering if I had to do anything to enable/install streaming in the sandbox.

    I am accessing the sandbox directly, i.e. not through the GUI.

    I log in to the VM, and try to run:

    hadoop jar contrib/streaming/hadoop-*streaming*.jar -file mapper.py -mapper mapper.py etc. etc.

    straight away it comes back with

    Not a valid JAR: /contrib/streaming/hadoop-*streaming*.jar

    I haven’t had much success with the GUI before, so just trying on the command line, but open to all suggestions!

    Hi Duncan,

    You shouldn’t need to do anything special to enable streaming in the sandbox, it is a standard single-node hadoop installation. It could be that due to the extra ‘*’ before streaming the .jar file couldn’t be found, can you try it without the ‘*’ before streaming? Also it probably woudn’t hurt to spell out the entire name of the .jar.
