Enable Routing To Same Coordinator For Cached SAML Auth Cookie

This option specifies whether the connector uses the cached SAML auth cookie to route to the same coordinator in subsequent connections.

  • Enabled (1)1: The connector uses the cached SAML auth cookie to route to the same coordinator in subsequent connections.
  • Disabled (0)0: The connector does not use the cached SAML auth cookie to route to the same coordinator in subsequent connections.

Note:  

  • This property is available only in Windows.
  • This property is active only when the configuration option Enable SAML Auth Cookie Caching is enabled.
  • This property addresses issues where SAML auth cookie caching may fail in an Impala cluster with active-active coordinators. If the cluster uses a coordinator-specific auth cookie mechanism, the cached SAML auth cookie is valid only for the issuing coordinator. When the cached cookie happens to be routed to a different coordinator, authentication fails. In this case, enabling this configuration ensures consistent routing to the correct coordinator. If the cluster uses a shared auth cookie mechanism across coordinators, the cached SAML auth cookie remains valid across all coordinators. In this case, disabling this configuration is recommended to avoid unnecessary routing and improve load balancing.
