Subject [jira] [Updated] (HDT-7) Job launching across versions
Date Thu, 29 May 2014 07:13:01 GMT

Rahul Sharma updated HDT-7:
---------------------------

    Attachment: 0001-Adding-hadoop2-based-on-2.2-version.patch

I have tried to achieve this one by creating different plugins for different versions of hadoop.
Basically the o.a.hdt.hadoop.release fragment contains the version specific stuff. I have
converted fragment into plugin, so that it does not export its classes to the host. Next I
added a new  plugin o.a.hdt.hadoop2.release on similar lines but with version 2.2. Since all
the required jars are packed in the plugin so it works out fine.  On the UI side a user needs
to select which version is being connected to.

Attached  is my first take at the issue. The  patch needs to  be improved at various levels,
it is WIP.
