Assignee: Thomas Tauber-Marshall
> Reuse hs2-http connections in impala-shell
> ------------------------------------------
>
> Key: IMPALA-9968
> URL: https://issues.apache.org/jira/browse/IMPALA-9968
> Project: IMPALA
> Issue Type: Task
> Components: Clients
> Affects Versions: Impala 4.0
> Reporter: Thomas Tauber-Marshall
> Assignee: Thomas Tauber-Marshall
> Priority: Major
>
> Currently, impala-shell creates a new connection for every request when
> running the hs2-http protocol. The reason for this is that we're using the
> default Thrift python HTTP client which is very basic and doesn't reuse
> connection for simplicity. It would be nice to reuse connections for
> performance reasons.
> We've already imported the code for it into Impala to make other changes, so
> it should be easy to further modify it to support connection reuse.
