(was: Query Plan Constantly Refreshes After Has Completed)
> Query Plan in Debug UI Constantly Refreshes After Completion
> ------------------------------------------------------------
>
> Key: IMPALA-9866
> URL: https://issues.apache.org/jira/browse/IMPALA-9866
> Project: IMPALA
> Issue Type: Bug
> Reporter: Shant Hovsepian
> Assignee: Shant Hovsepian
> Priority: Major
> Fix For: Impala 4.0
>
>
> The query plan debug page fetches and re-renders the query plan graph every
> second event after the query has completed.
>
> For large query plans this makes interacting with the graph much slower and
> resource intensive on the user's web browser. Also it put a strain on the
> coordinator node as large query plans can be several megabytes in size and is
> constantly re-transmitted while the user has the query plan page open.
