Subject Submitting multiple Pig Scripts on the same Session
Date Fri, 18 Jan 2019 20:20:41 GMT
Hi!

We are developing an application that is looking for new files on a folder,
running a few Pig Scripts to prepare those files and, finally, loading them
into our database.

The problem is that, for small files, the time that Pig / Tez / Yarn take
to create a new application master and spawn new containers is way longer
than the time it takes processing.

Since Tez Sessions already allows a single Pig script to run multiple DAGs
against the same application master, is there a way to reuse that
application master and it´s containers for multiple Pig Scripts submissions
?

Regards,

Diego
