    Description

      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.
