--------------------------------------
Assignee: Joe McDonnell
> Enable long polling by default
> ------------------------------
>
> Key: IMPALA-14686
> URL: https://issues.apache.org/jira/browse/IMPALA-14686
> Project: IMPALA
> Issue Type: Improvement
> Components: Clients, Frontend
> Reporter: Michael Smith
> Assignee: Joe McDonnell
> Priority: Major
>
> IMPALA-13294 added support for long polling in Impala and impala-shell. This
> behavior is strictly better than the current behavior, allowing Impala
> clients to eliminate delays in completing show queries and making the
> experience of using Impala more responsive.
> On the fringes, clients that don't know about long polling may have slightly
> different timing with certain queries, as the RPC may wait the
> {{long_polling_time_ms}} timeout then do its own sleep.
> Set {{long_polling_time_ms}} to a short period - say 100ms - to provide
> better support for low-latency queries.
