---------------------------------------
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}
