Rajiv Ramachandran updated MAPREDUCE-7461:
------------------------------------------
Description:
The following tests depend on underlying implementation orders which are not
guarenteed, while comparing the contents of the generated XML response.
_org.apache.hadoop.mapreduce.v2.app.webapp.TestAMWebServicesJobs#testJobIdXML_
_org.apache.hadoop.mapreduce.v2.app.webapp.TestAMWebServicesJobs#testJobsXML_
_org.apache.hadoop.mapreduce.v2.hs.webapp.TestHsWebServicesJobs#testJobIdXML_
The test attempts to send a HTTP GET request to a specific URL and expects a
response in XML format. However, XML response order is not necessarily
guaranteed. When comparing the the XML contents, The `<name>` tag occurs in
multiple places inside <job> field. However, the root element within <job> is
not always compared due to non-deterministic order. The [getXmlString
utility|https://github.com/kavvya97/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/test/java/org/apache/hadoop/yarn/webapp/WebServicesTestUtils.java#L78]
always takes the first <name> tag irrespective of whether it is nested or in
root which causes the test to become flaky.
