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.
> Support setting execution bit for regular files

> 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.
