Storm workers not starting


My Nimbus host and supervisor run properly. When I submit a wordcount topology to the Nimbus host it successfully upload. After uploading topology supervisor giving error

kill: No such process

When I check the worker-6001.log and 6002.log I found a following error:

I used this blog as a example.


Solution

  • The resolution depends on the version of Storm you're running.


    [EDIT]

    Storm 0.9.1 has just been released today (22nd Feb 2014): release notes mention zeroMQ dependencies are now by default replaced by Netty

    https://git-wip-us.apache.org/repos/asf?p=incubator-storm.git;a=blob_plain;f=CHANGELOG.md;hb=254ec135b9a67b1e7bc8e979356274aee2e7d715


    The installation instructions of the previous version (I successfully used those for 0.8.2 in the past) are here, they indeed mention zeroMq and jzmq as dependencies:

    https://github.com/nathanmarz/storm/wiki/Setting-up-a-Storm-cluster

    The installation instructions of 0.9.0.1 are here: they do not mention zeroMQ nor jzmq:

    http://storm.incubator.apache.org/documentation/Setting-up-a-Storm-cluster.html

    According to the release notes of Storm 0.9.0, we now have the choice between Netty and ZeroMQ for tuple transport, so in theory you should be able to solve this issue by upgrading to 0.9.0.1, not install zeroMQ nor jzmq and configure storm as mentioned here:

    (dawn, not allowed to post a 3rd link, ok, the release notes are on the Storm blog, in the Storm incubator apache web site ^__^)
