Description

I've continued working on the umbrella JIRA SQOOP-2468 by injecting various invalid JSON snippets and I've noticed that is extremely easy to get NullPointerException. That is because we're anticipating certain structure in the JSON and we're not properly checking whether it's there or not.

I would like to fix that by introducing util method that will properly verify if given key is available and whether it's of proper class instead of throwing not useful NullPointerException.
