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.
