Rajat Khandelwal commented on LENS-743:
---------------------------------------
I'm thinking Lens server will consult the driver regarding the retry mechanism.
Driver will decide based on failure type. Policy can be exponential backoff or
immediate retry. Only High level constructs but I feel that'll get clearer as I
dive into coding.
> 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.
