Subject [jira] [Commented] (HADOOP-12296) when setnetgrent returns 0 in linux, exception should be thrown
Date Tue, 04 Aug 2015 13:57:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14653674#comment-14653674

Chang Li commented on HADOOP-12296:
-----------------------------------

[~aw] thanks for providing opinion. But I still think it's reasonable to thrown an exception
because when setnetgrent returns 0 in linux it's not saying the netgroup is empty, but it's
actually saying the passed netgroup name is invalid (misconfigured) or if any error occurred.

> In linux, setnetgrent returns 0 in linux when something wrong is happen, such as out
of memory, unknown group, unavailable service, etc. So errorMessage should be set and exception
should be thrown
