> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 0.20.2
> Reporter: sam rash
> Assignee: sam rash
> Attachments: hadoop-6762-1.txt, hadoop-6762-10.txt,
> hadoop-6762-2.txt, hadoop-6762-3.txt, hadoop-6762-4.txt, hadoop-6762-6.txt,

> If a single process creates two unique fileSystems to the same NN using
> FileSystem.newInstance(), and one of them issues a close(), the leasechecker
> thread is interrupted. This interrupt races with the rpc namenode.renew()
> and can cause a ClosedByInterruptException. This closes the underlying
> channel and the other filesystem, sharing the connection will get errors.
