Description

I had some manual setup that I did to create a docker network and set INTERNAL_LISTEN_HOST as the gateway. I think we could automate it with some logic like the following:

docker network create -d bridge impala-cluster
IMPALA_NETWORK_GATEWAY=$(docker network inspect impala-cluster | grep -o '"Gateway": "[0-9\.]*"' | grep -o "[0-9.]*")
echo "export INTERNAL_LISTEN_HOST=${IMPALA_NETWORK_GATEWAY}" >> bin/impala-config-local.sh
echo 'export DEFAULT_FS=hdfs://${INTERNAL_LISTEN_HOST}:20500' >> bin/impala-config-local.sh
