Run a pig script from a oozie as a java activity

[Jakub Stransky <st...@gmail.com>]

Hello experienced users,

I have a pig script where I need dynamically change input parameters e.g.
input paths and for every single combination I need to submit a pig
script.  Esentially  I am walking around missing features of loops or for
cycles. The only solution which came to my mind is put the whole dynamic
logic in java activity just need to fine a way how to submit a pig script
from java.

Could someone please point me to right direction?

Many thanks
Jakub

The alternative is to creat new workflows or summit workflow with different parameters programmatically via Oozie API.

The book from Boris, Kevin and Alexy is very helpful on this regard.
