[jira] [Updated] (HIVE-13150) When multiple queries are running in the same session, they are sharing the same HMS Client.

     [ https://issues.apache.org/jira/browse/HIVE-13150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aihua Xu updated HIVE-13150:
----------------------------
    Description: 
Seems we should create different HMSClient for different queries if multiple queries are executing in the same session in async at the same time to have better performance.
Right now, we are unnecessarily use one HMSClient and we have to make HMS calls in sync among different queries.
