Currently, the retries and backoff seconds are hard-coded in the ImpalaErrorHandler, which is not ideal, as there might be users who want to have specific values for these properties.
This change adds two new configuration variables,
IMPALA_RETRIES_ON_ERROR
andIMPALA_ERROR_BACKOFF_SECONDS
, which are to be used for configuring how many times a failed query is to be retried, and how big the backoff should be.
