2. Change PasswordAuthentication to yes. This can be changed back to no if ssh keys are setup.

	#Steps to merge/close pull requests with two main branches

	As NiFi now has a 1.0 (master) and 0.x (support) branch, pull requests (PR) must be applied to both. Here is a step-by-step guide for committers to ensure this occurs for all PRs.

	1. Check out the latest master
	``` $ git checkout master
	$ git pull upstream master
	```

	2. Check out the PR (example #327). This will be in `detached-HEAD` state. (Note: You may need to edit the `.git/config` file to add the `fetch` lines [below](#fetch))
