  • Flink clusters in security mode can be interconnected with Elasticsearch clusters in both security mode and normal mode.
    When the Flink cluster in security mode is interconnected with an Elasticsearch cluster in normal mode, set the following parameters:
    1. Log in to FusionInsight Manager, choose Cluster > Services > Flink. Click Configurations > All Configurations, search for the es.security.indication parameter, and set its value to false for both the FlinkResource and FlinkServer roles.
    2. On the Dashboard page, choose More > Restart Service to restart Flink.
  • Flink clusters in normal mode can be interconnected with Elasticsearch clusters in normal mode as well.
