> Issue Type: Improvement

> 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.
