> [~aihuaxu] I see this commit made via HIVE-11488. I see that query id is
> being reused across queries. This defeats the purpose of a query id. I am not
> sure what the purpose of the change in that jira is but it breaks the
> assumption about a query id being unique for each query. Please take a look
> into this at the earliest.
