Todd Lipcon commented on HADOOP-6762:
-------------------------------------
Note that one of the path segments differs between the two URLs. I think it
just pulls an attachment ID from that path segment and downloads that,
regardless of the name at the end of the path (your two wget urls have the same
path segment, I guess you manually edited the last bit?)
> exception while doing RPC I/O closes channel

> 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.
