Subject Re: Web interface to submit jobs
Date Mon, 09 Nov 2015 09:40:25 GMT
Hi Sachin,

Thank you for your work. From the screenshots it looks like you replicated
the behavior of the old web client. I would like to take a look at the
actual code. There are at least three things we need to work on next:

1. Introduce a config variable to disable the job submission page
2. Add an upload functionality
3. Integrate with YARN (respect the correct directories to write into).

As for the parameter tool, this is an additional feature and is IMHO not
required as a first step.

Cheers,
Max
