-------------------------------------------------------------
Configurations
* Retry attempts (driver specific/ Error specific or common?)
* Wait duration between retries (can have a default value and also based on
error type)
How will the APIs respond ?
* query details : show details for all attempts
* query status : show status of latest attempt
* show logs : shows logs for all attempts

> 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.
