Review Comment:
> In HiveSessionImplwithUGI, we set the HiveServer2ImpersonationToken token
before the SessionState starts, will the HiveClientImpersonationToken override
the HiveServer2ImpersonationToken?
If hiveserverquery,will return directly
```
private void setHiveMetastoreDelegationTokenToUGI() {
if (this.isHiveServerQuery) {
return;
}
...
}
```
