> Fix order of actual and expected expression in assert statements which gives misleading
message when test case fails. Attached file has some of the places where it is placed wrongly.
> {code:java}
> [ERROR] testNodeRemovalGracefully(org.apache.hadoop.yarn.server.resourcemanager.TestResourceTrackerService)
 Time elapsed: 3.385 s  <<< FAILURE!
> java.lang.AssertionError: Shutdown nodes should be 0 now expected:<1> but was:<0>
> {code}
> For long term, [AssertJ|http://joel-costigliola.github.io/assertj/] can be used for new
test cases which avoids such mistakes.
> This is a follow-up jira for the hadoop-common project.
