> TajoMaster is a Single Point of Failure in a Tajo Cluster because TajoMaster
> is the central controlling entity for all components of the Tajo system.
> TajoMaster failure prevents clients from submitting new queries to the
> cluster, and results in the disruption of the ability to run insert overwrite
> queries because the TajoWorker can’t apply its statistical information to
> CatalogStore. Therefore, the high-availability (HA) of TajoMaster is
> essential for the high-availability of Tajo generally.
