Subject [jira] [Updated] (HADOOP-10989) Work around buggy getgrouplist() implementations on Linux that return 0 on failure
Date Fri, 22 Aug 2014 04:07:13 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10989?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Nauroth updated HADOOP-10989:
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 2.6.0
                   3.0.0
           Status: Resolved  (was: Patch Available)

Once again, the release audit warnings are unrelated.  No new tests are included, because
this was covered sufficiently by existing unit tests.  I ran on both Linux and FreeBSD.

I committed this to trunk and branch-2.  Thanks again to Colin for the code review.

> HADOOP-10781 corrected the handling of the return value from {{getgrouplist}} to work
on FreeBSD.  However, it also regressed fixes that had been put in place to work around issues
with {{getgrouplist}} on Linux.  This issue will restore that behavior, but still retain compatibility
with FreeBSD.
