> Can you add a test for this, considering now we are propagating the real
error back to the client.
>
> I think if the actual error is being thrown in that case on the client
side we can live with just the message, rather than having the entire trace.
ok, I'll add a test class for this PR later.
Besides, It's not HDFSClient that's actually causing an error, but
NameNodeFsck, which uses a DFSClient object that doesn't support Kerbeors. And
I will submit another PR to solve the NameNodeFsck's bug later.
> Fix namenode fsck swallows the exception stacktrace, this can help us to
> troubleshooting log.

> When I used `hdfs fsck /xxx.txt -move`, missing error, but I can't kown the
