> The timeout is introduced in HIVE-9079. Previously the driver may hang. This
> seems to be a robustness issue of RSC. Hanging isn't good, but timeout isn't
> good either unless there is some network issue, which doesn't seem to be case
> here. [~chengxiang li]/[~vanzin], could we get the bottom of this? Increase
> the timeout value if necessary.
