Unable to set Spark Master

[Jakub Liska]

Hey,

I'm starting zeppelin.sh from within docker container:

/usr/bin/docker run \
    -p 4040:4040 \
    -p 8080:8080 \
    -e ZEPPELIN_JAVA_OPTS="-Dspark.executor.memory=5g" \
    -e ZEPPELIN_PORT=8080 \
    -e ZEPPELIN_NOTEBOOK_DIR=foo/bar \
    -e MASTER=spark://${SPARK_MASTER_IP}:7077 \
    foo/zeppelin

And since my Master IP is dynamic, I need to set it via Environment
variable as you can see above...

root@3d1c2c3bc389:/opt/zeppelin# printenv | grep MASTER
MASTER=spark://10.1.4.4:7077

But Zeppelin doesn't use it, I see this in it's logs :

------ Create new SparkContext local[*] -------

Any idea what might be wrong? I cannot use zeppelin-env.sh because the IP
address is dynamic.
