----------------------------------------------
[~prongs] Can you also update (how?) the flow changes if server restarts in
between a query just failed without exhausting retries and more cases ?
> Query failure retries for transient errors

> There have to be retries for query failures for transient errors like network
> errors (Hive server not reachable/ Metastore not reachable/ DB not
> reachable). Retries should be available for each phase - submission,
> execution, updating status, fetching results and formatting.
> Right now, any such failure results in marking query as failed.
