---------------------------------------

             Summary: Can not start HA cluster with start-cluster.sh
                 Key: FLINK-6000
                 URL: https://issues.apache.org/jira/browse/FLINK-6000
             Project: Flink
          Issue Type: Bug
          Components: Startup Shell Scripts
    Affects Versions: 1.2.0
            Reporter: Dawid Wysakowicz


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:
{code}
high-availability: zookeeper
...
{code}

in conf/masters:
{code}
localhost:8081
localhost:8082
{code}

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:

{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
{code}
