Ajay Yadava commented on FALCON-1748:
-------------------------------------

I had committed it to 0.9 yesteray but due to some connectivity issues couldn't update the JIRA. It was a blocker for 0.9 release since several days so committed it. I also took liberty with [~Praveen]'s permission to fix a few things in this patch (including a typo in the FalconClient) Will upload the patches which got committed for future reference.

> Since only server side refactoring is done for error handling FALCON-1705, this has become a blocker for 0.9 release. All the client exceptions now throw the following exception irrespective of what the error is :
