Subject [jira] [Created] (YARN-535) TestUnmanagedAMLauncher can corrupt target/test-classes/yarn-site.xml during write phase, breaks later test runs
Date Wed, 03 Apr 2013 14:55:15 GMT
Steve Loughran created YARN-535:
-----------------------------------

             Summary: TestUnmanagedAMLauncher can corrupt target/test-classes/yarn-site.xml
during write phase, breaks later test runs
                 Key: YARN-535
                 URL: https://issues.apache.org/jira/browse/YARN-535
             Project: Hadoop YARN
          Issue Type: Bug
          Components: applications
    Affects Versions: 3.0.0
         Environment: OS/X laptop, HFS+ filesystem
            Reporter: Steve Loughran
            Priority: Minor


the setup phase of {{TestUnmanagedAMLauncher}} overwrites {{yarn-site.xml}}. As {{Configuration.writeXml()}}
does a reread of all resources, this will break if the (open-for-writing) resource is already
visible as an empty file. 

This leaves a corrupted {{target/test-classes/yarn-site.xml}}, which breaks later test runs
-because it is not overwritten by later incremental builds, due to timestamps.
