[jira] [Commented] (HADOOP-9638) parallel test changes caused invalid test path for several HDFS tests on Windows

    [ https://issues.apache.org/jira/browse/HADOOP-9638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13680502#comment-13680502 ] 

Chris Nauroth commented on HADOOP-9638:
---------------------------------------

HADOOP-9287 changed {{FileSystemTestHelper}} to allow passing an override of the test root to its constructor.  This supports overriding to paths of the form /tmp/<test name> for HDFS.  It looks like we missed {{FileContextTestHelper}} though, so we'll likely need similar changes for that.  An example of a failing test is {{TestFcHdfsCreateMkdir}}.

[~aklochkov], are you interested in doing a follow-up patch?  If not, I can take it.  I'm also happy to help with testing.

> HADOOP-9287 made changes to the tests to support running multiple tests in parallel.  Part of that patch accidentally reverted a prior change to use paths of the form "/tmp/<test name>" when running tests against HDFS.  On Windows, use of the test root will contain a drive spec (i.e. C:\dir), and the colon character is rejected as invalid by HDFS.
