Hi guys, I configured Spark with the configuration in spark-env.sh: export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=host1:2181,host2:2181,host3:2181 -Dspark.deploy.zookeeper.dir=/spark"
And I started spark-shell on one master host1(active): MASTER=spark://host1:7077,host2:7077 bin/spark-shell I stop-master.sh on host1, then access host2 web ui, the worker successfully registered to new master host2, but the running application, even the completed applications shows nothing, did I missing anything when I configure spark HA ? Thanks !
