Rajat Khandelwal commented on LENS-743:
---------------------------------------
I'm thinking creating a new query handle will result in addition of a lot of
book-keeping code.
Instead of that, I'm thinking we should add a retry-count field in query
context. The email failure message will be sent to the user as usual. User will
be notified that we're re-trying the query. Query handle will be same, all the
state transitions will be same, just that after FAILED, it'll move to
QUEUED/RUNNING state.

> 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.
