Re: Atomic file updates

[Jay Vyas <jayunit100@xxxxxxxxx>]

For vanilla apps that are doing stuff in gluster, you normally do it through a fuse mount. 

mount -t glusterfs localhost:HadoopVol /mnt/glusterfs

But in your case, you might want to do some strict consistency settings to make it atomic:

mount -t glusterfs localhost:HadoopVol -o  entry-timeout=0,attribute-timeout=0 /mnt/glusterfs

This will make sure that everything is refreshed when you look up files.  This strategy has solved our eventual consistency requirements for the hadoop plugin.
