> TestJobImpl->testJobNoTasks fails ..
> ------------------------------------
>
> Key: MAPREDUCE-5136
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5136
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.0.3-alpha
> Environment: Linux + IBM JAVA 6
> Reporter: Amir Sanjar
> Assignee: Amir Sanjar
> Attachments: MAPREDUCE-5136.patch

>
> I am not sure if this is a testcase or a design issue. During execution of
> TestJobImpl->testJobNoTasks() there is an assertion made based on the order
> of key/value pairs stored in adjacency list. However adjacency list was
> created by Configuration->getValByRegex() as a HashMap (order is not
> guaranteed):
> Testcase:
> JobSubmittedEventHandler jseHandler = new
> JobSubmittedEventHandler("testId",
> "testName", "testNodeName", "\"key2\"=\"value2\" \"key1\"=\"value1\"
> ");
> ....
> ....
> try {
> Assert.assertTrue(jseHandler.getAssertValue()); <===
> Configuration->getValByRegex():
> public Map<String,String> getValByRegex(String regex) {
> Pattern p = Pattern.compile(regex);
> Map<String,String> result = new HashMap<String,String>(); <=======
>
> as we all know, HashMap makes absolutely no guarantees about the iteration
> order. It can (and will) even change completely when new elements are added.
> Changing HashMap to LinkedHashMap fixes the ordering inconsistency, however
> with a small performance side effect.
