Subject [jira] [Commented] (HDFS-4659) Support setting execution bit for regular files
Date Tue, 09 Apr 2013 15:46:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4659?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626730#comment-13626730

Daryn Sharp commented on HDFS-4659:
-----------------------------------

I'm not sure that allowing sticky bit on file should now be allowed.  Older *nix flavors used
it to keep the text segment of an executable in swap.  Linux has never supported it, and I
believe most other OSes dropped it.

> By default regular files are created with mode "rw-r--r--", which is similar as that
on many UNIX platforms. However, setting execution bit for regular files are not supported
by HDFS. 
> It's the client's choice to set file access mode. HDFS would be easier to use if it can
support it, especially when HDFS is accessed by network file system protocols. This JIRA is
to track the change to support execution bit.
