Subject [jira] [Updated] (HADOOP-8958) ViewFs:Non absolute mount name failures when running multiple tests on Windows
Date Mon, 29 Oct 2012 07:47:11 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8958?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chris Nauroth updated HADOOP-8958:

    Attachment: HADOOP-8958.patch

The attached patch fixes this problem.  I'd like to start the patch on trunk and then immediately
merge to branch-trunk-win after commit.

The problem was that the tests attempted to determine a testing mount point for ViewFS by
taking the testing path and trimming the first segment from that.  On Windows, if the testing
path is /C:/build/test, then this logic yields /C:, which is not an absolute path.  The ViewFS
mount point must be an absolute path.  I changed this logic to use Path and walk up the directory
hierarchy to the shortest absolute path that is not root.
