> Project: Hadoop Map/Reduce

> Components: mrv2
> Affects Versions: 2.5.0
> Reporter: Thomas Graves

>
> Looking at the JobSubmitter.compareFs it doesn't look like it properly
> handles HA namespaces. The code tries to lookup the hostname using
> InetAddress.getByName, but if you are using namespaces this is going to fail
> and its going to copy the file when it doesn't need to.
