Ayush Saxena commented on HDFS-14741:
-------------------------------------
Thanx [~xuzq_zander] for the patch, fix LGTM.
I guess for the test you can use the existing mount entries only, add a file
and delete it in the finnally, there are two mount entries / pointing to ns0-/
and ns1-/ and /same pointing to ns0-/ and /target-ns0-/
{code:java}
247 RouterContext rc = getRouterContext();
248 DistributedFileSystem routerFs =
249 (DistributedFileSystem) rc.getFileSystem();
{code}
Can use {{DistributedFileSystem routerFs = (DistributedFileSystem)
getRouterFileSystem();}}
For FsDataOutputStream we can use try with resources rather than handling this
much.

> RecoverLease should be return false when the file is open or be writing in
> multiple destinations.
> Liks this:
> Mount point has multiple destination(ns0 and ns1).
> And the file is in ns0 but it is be writing, ns1 doesn't has this file.
> In this case *recoverLease* should return false instead of throw
> FileNotFoundException.
