How to import existing workflow package into hortonworks sandbox?

  • #55876

    I am not able to import my oozie package into the hortonworks sandbox. Any help is highly appreciated!

    I have the following package in the local

    - MyProject
    -- workflow.xml
    -- lib
    --- myLib.jar
    --- otherLib.jar

    First I tried to import it into hortonworks sandbox via command-line:

    oozie job -verbose -oozie -config /home/hue/ -run

    Where is


    and this gives me

    Error E0701: XML schema error, Content is not allowed in prolog.

    I checked there is no BOM in my workflow file and was able to successfully validate it via

    oozie validate workflow.xml

    So I give up command-line and tried import it from web UI. I can import only workflow.xml successully. However I don’t know how to add myLib.jar and otherLib.jar into the classpath. I tried zipping lib folder and adding the resulting package to “Workflow resource archive (zip)” during import, but I get following exception:

    get() returned more than one Node -- it returned 2! Lookup parameters were {'name': 'kill', 'workflow': <Workflow: mc2 - hue>}

    click on more info:

    /usr/lib/hue/apps/oozie/src/oozie/views/ 205 import_workflow
    /usr/lib/hue/apps/oozie/src/oozie/ 591 import_workflow
    /usr/lib/hue/apps/oozie/src/oozie/ 127 _save_links
    /usr/lib/hue/apps/oozie/src/oozie/ 241 _node_relationships
    /usr/lib/hue/build/env/lib/python2.6/site-packages/Django-1.2.3-py2.6.egg/django/db/models/ 132 get
    /usr/lib/hue/build/env/lib/python2.6/site-packages/Django-1.2.3-py2.6.egg/django/db/models/ 343 get

    That’s all I have. Any suggestions?

    Hi Dzianis,
    Can you validate you are able to run the examples provided as part of the sandbox by executing the following:

    su oozie
    cd /usr/share/doc/oozie-
    oozie job -oozie -config examples/apps/map-reduce/ -run

    More information can be found here ->

    Once you get a sample running, you should be able to use that as a baseline for getting your oozie job running.

    Thanks, iandr413. I was able to run example. I was trying to launch app from archive before, so I extracted files from archive and pointed my to the folder and it works! However the process looks too complicated right now:
    1. I first package my app via mvn
    2. Copy workflow.xml and libs into HDFS
    3. Copy into sandbox’s filesystem
    4. Launch from sandbox terminal

    Any way I can simplify it? Ideally it will be great to import my package from we UI.
