Subject [jira] [Commented] (MAPREDUCE-4987) TestMRJobs#testDistributedCache fails on Windows due to unexpected behavior of symlinks
Date Thu, 07 Feb 2013 18:19:14 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4987?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573742#comment-13573742

Vinod Kumar Vavilapalli commented on MAPREDUCE-4987:
----------------------------------------------------

But symlinks CAN be used for functional purposes i.e linking to libraries etc. ? If so we
can just do the platform check in the test-case.

> 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.
