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 to use one HMSClient and we have to make HMS
calls in sync among different queries.
was:
HMS connection leak has been addressed for the session thread, task threads if
the execution is run in parallel.
While if we execute the queries in async, we will run the queries in separate
threads and the HMS connections there are not released.
> When multiple queries are running in the same session, they are sharing the
> same HMS Client.
