------------------------------------
Hi [~lirui], Thanks for the investigation. I'm wondering if that dependency can
be excluded in Hive's build? While the latest patch builds, it changes Hive's
existing dependency, which might cause some problem.
Also, we are upgrading the following libraries. I'm not sure If it's absolutely
necessary. From my build alone, it seems not. [~Ferd], any thoughts?
