[jira] [Updated] (MAPREDUCE-4987) TestMRJobs#testDistributedCache
fails on Windows due to unexpected behavior of symlinks
[ https://issues.apache.org/jira/browse/MAPREDUCE-4987?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chris Nauroth updated MAPREDUCE-4987:
-------------------------------------
Target Version/s: 3.0.0 (was: trunk-win)
Affects Version/s: (was: trunk-win)
3.0.0
Assignee: Chris Nauroth
In addition to the symlink problem mentioned earlier, I've discovered that there are also some problems with the logic for packaging the classpath into a jar manifest on Windows. This can cause us to miss distributed cache entries on the classpath. I'm going to try to address all of this in the same patch.

> On Windows, {{TestMRJobs#testDistributedCache}} fails on an assertion while checking the length of a symlink. It expects to see the length of the target of the symlink, but Java 6 on Windows always reports that a symlink has length 0.
