Subject [jira] [Commented] (HADOOP-10989) Work around buggy getgrouplist() implementations on Linux that return 0 on failure
Date Thu, 21 Aug 2014 22:16:11 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10989?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14106045#comment-14106045

Colin Patrick McCabe commented on HADOOP-10989:
-----------------------------------------------

Weird.  I was expecting a third-party library (that's what it's been in the past for us),
but I guess even nslcd can have bugs :P

Thanks, Chris.  +1

> 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.
