Error with logstash

[sdasara95]

This is for Analytics Server Docker
I'm getting the following error when running the start.sh script.
I believe it's because logstash requires spark-master but spark-master is not built.

The error is as follows:

standard_init_linux.go:211: exec user process caused "exec format error" ERROR: Service 'logstash' failed to build: The command '/bin/sh -c logstash-plugin install logstash-filter-json logstash-output-kafka' returned a non-zero code: 1 Error: No such container: spark-master
