Yi Liu commented on HADOOP-12178:
---------------------------------
Steve, sorry for late response.
I agree with you not all exceptions indicates a problem with SASL connection,
and some can be rethrown. Seems {{setupSaslConnection}} only throws IOException
which is must handled, but not very sure if there are other exceptions thrown
out.
To be safety, could we keep the
{code}
} catch (Exception ex) {
{code}
Thanks.

> If there's any problem in the constructor of {{SaslRpcClient}}, then IPC
> Client throws an NPE rather than forwarding the stack trace. This is because
> the exception handler assumes that {{saslRpcClient}} is not null, that the
> exception is related to the SASL setup itself.
> The exception handler needs to check for {{saslRpcClient}} being null, and if
> so, rethrow the exception
