> DNS query on YARN Registry DNS got connection timed out at times.
>
> After checking logs on registry dns, we found the cause that size of UDP
> Response is greater than Preallocated Byte buffer(4096)
>
> We added failsafe case by returning input query with TC flag so that client
> can know they should retried using TCP protocol.
>
>
> We found the problem and patched our cluster on 3.1.2 but it seems trunk
> still has the same problem.
> I attached patch based on the trunk.
>
> Thanks!
