      Description

      Right know it is impossible to start a cluster in zookeeper HA mode as described in the documentation by setting:

      in con/flink-conf.yaml:

      high-availability: zookeeper
      ...
      

      in conf/masters:

      localhost:8081
      localhost:8082
      

      The problem is with the bin/config.sh file. If value "zookeeper" is read from config file the variable HIGH_AVAILABILITY will be reset to "none" with the else branch. See the below code:

      if [ -z "${HIGH_AVAILABILITY}" ]; then
           HIGH_AVAILABILITY=$(readFromConfig ${KEY_HIGH_AVAILABILITY} "" "${YAML_CONF}")
           if [ -z "${HIGH_AVAILABILITY}" ]; then
              # Try deprecated value
              DEPRECATED_HA=$(readFromConfig "recovery.mode" "" "${YAML_CONF}")
              if [ -z "${DEPRECATED_HA}" ]; then
                  HIGH_AVAILABILITY="none"
              elif [ ${DEPRECATED_HA} == "standalone" ]; then
                  # Standalone is now 'none'
                  HIGH_AVAILABILITY="none"
              else
                  HIGH_AVAILABILITY=${DEPRECATED_HA}
              fi
           else
               HIGH_AVAILABILITY="none" <-- it exits here
           fi
      fi
