Good catch of the bug. [~santhk] I think you are right in that a JobUpdate of a pending job, that again puts in a pending state, would cause this. One way to go about this is to remove the Veto from NearestFit once a pending job has been updated. That way if the updated Job goes into pending state, then there won't be any clash when /pendingTasks api is accessed.

> When we have multiple TaskGroups that have same key but different TaskConfigs, the /pendingTasks endpoint will gives a 500 HTTP Error.
> This bug seems to be related to a recent commit (Added the 'reason' to the /pendingTasks endpoint)(https://github.com/apache/aurora/commit/8e07b04bbd4de23b8f492627da4a614d1e517cf1). 
> Attached were a screenshot of the /pendingTasks endpoint.
