Subject [jira] [Commented] (HADOOP-10527) Fix incorrect return code and allow more retries on EINTR
Date Wed, 23 Apr 2014 13:26:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13978181#comment-13978181
] 

Kihwal Lee commented on HADOOP-10527:
-------------------------------------

The information I looked at was based on POSIX.1-2001. In POSIX.1-2008, it was revised like
this:
{panel}
 A call to sysconf(_SC_GETGR_R_SIZE_MAX) returns either -1 without 
 changing errno or an initial value suggested for the size of this buffer.
{panel}

Thanks for the reviews, Colin.

> After HADOOP-10522, user/group look-up will only try up to 5 times on EINTR.  More retries
should be allowed just in case.
> Also, when a user/group lookup returns no entries, the wrapper methods are returning
EIO, instead of ENOENT.
