5. build Sleepy framework

   mvn clean package

6. Run Sleepy framework

   java -jar mesos-rxjava-example/mesos-rxjava-example-framework/target/mesos-rxjava-example-framework-0.1.0-SNAPSHOT-jar-with-dependencies.jar \
      http://127.1.0.3:5050/api/v1/scheduler \
      1 \

Could we add ZK link support also? Like

 java -jar mesos-rxjava-example/mesos-rxjava-example-framework/target/mesos-rxjava-example-framework-0.1.0-SNAPSHOT-jar-with-dependencies.jar \
    zk://zk.host.com:2181/mesos

[BenWhitehead]

ZK integration falls outside the design of the http api and should not have to be integrated with per Master Detection

Makes sense, got it.
