xuzq commented on HDFS-14741:
-----------------------------
Thanks [~ayushtkn] for the comment. Please review [^HDFS-14741-trunk-004.patch].
{quote} __ For FsDataOutputStream we can use try with resources rather than
handling this much.
{quote}
Because it will be throw IOException("_Commit or complete block
blk_1073741825_1001, whereas it is under recovery_") when close, and it will be
throw FileNotFoundException() in the trunk code.
I don't have good idea to identify the two exceptions when use try with
resources, so i use try with finally and close the FsDataOutputStream and only
ignore the _complete exception._

> 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.
