["Aihua Xu (JIRA)" <ji...@apache.org>]

Aihua Xu updated HIVE-13129:
----------------------------
    Attachment: HIVE-13129.2.patch

Talked to Chaoyu offline. He is planning to use the connection for delegation token. 

So patch-2 moves the closure to the stop() method. The resources would be released eventually when the HS2 closes, but seems still a good idea to close them immediately when it's no use especially for the case of multiple HS2 instances.

> HIVE-12790 fixes the HMS connection leaking. But seems there is one more connection from CLIService.
> The init() function in CLIService will get info from DB but we never close the HMS connection for this service main thread.  
> {noformat}
>     // creates connection to HMS and thus *must* occur after kerberos login above
>     try {
>       applyAuthorizationConfigPolicy(hiveConf);
>     } catch (Exception e) {
>       throw new RuntimeException("Error applying authorization policy on hive configuration: "
>           + e.getMessage(), e);
> {noformat}
