Aihua Xu commented on HIVE-13286:
---------------------------------
QueryId should be unique. The user overwritten queryId is for the user to
provide meaningful queryId if the user wants to and the user needs to make sure
it's unique.
If the user doesn't overwrite the queryId, then hive will generate one as
before.
> Query ID is being reused across queries

> [~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.
