We are trying to setup a single node Kubernetes cluster.
1 Job Manager and 1 Task Manager.
Before we were getting an error, and we followed this thread.
http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Flink-1-5-4-issues-w-TaskManager-connecting-to-ResourceManager-td23298.html
After following the above mentioned archive , we have used the following
commands to startup the Flink services :
${FLINK_HOME}/bin/jobmanager.sh start-foreground
${FLINK_HOME}/bin/taskmanager.sh start-foreground
Previously jobmanager was being started as :
${FLINK_HOME}/bin/jobmanager.sh start-foreground cluster
${FLINK_HOME}/bin/taskmanager.sh start-foreground
It removed that error and now we are getting this error as shown below.
We searched all archives and have a dead end.
We have set up all ports correctly. Flink version used is 1.6.2.
Thanks in advance.
