Hi
I configured Zookeeper with four nodes for my Mesos cluster with Marathon. When I ran Flink Json file on Marathon, it was run without problem. But, when I entered IP of my two slaves, just one slave shew Flink UI and another slave shew this error:
Service temporarily unavailable due to an ongoing leader election. Please refresh
I checked "zookeeper.out" file and it said that :
