Summary: Fix order of actual and expected expression in assert
statements
Key: MAPREDUCE-7197
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7197
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 3.2.0
Reporter: Adam Antal
Assignee: Adam Antal
Attachments: old-approx-from-HADOOP-12693
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 on the fix for the MR project.
