Rajat Khandelwal commented on LENS-743:
---------------------------------------
One major thing to consider is whether in an event of re-try, the query go to
the queue Or it should be directly launched on driver.
I believe that the retry should not start from the beginning, it should just
re-launch on driver. But that has the hazard of one query taking up major chunk
resources in retries hindering the execution of other queries. Would be helpful
if other can share their thoughts on this.

> 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.
