Everything works well through hive-cli and beeline; however, I'm facing a strange behavior
through Hue.
> I can have a lot of client connections (these can reach 600) and after a day, the client
connections fail. But this is not the case for all clients connection attempts.
> When it fails, I have the following logs on the HiveServer2:
