Review comment:
> Hi @AngersZhuuuu, while applying your patch I found a bug here,
`session.getSessionHandle` will have an exception because `session` is `null`.
>
> Then I moved `session = HiveSessionProxy.getProxy(sessionWithUGI,
sessionWithUGI.getSessionUgi)` to before the if statement will solve this issue.
yea， some mistake, here is just a way to implement this. If you have
interesting in this way , you can see this
