Summary: [hadoop-common] Fix order of actual and expected
expression in assert statements
Key: HADOOP-16510
URL: https://issues.apache.org/jira/browse/HADOOP-16510
Project: Hadoop Common
Issue Type: Sub-task
Affects Versions: 3.2.0
Reporter: Adam Antal
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.
