About the type of number of containers for TaskManagers, it should be
optional because the user can the Scala Shell without specifying the number
when the user wants to connect already deployed YARN cluster.
(`bin/start-scala-shell.sh yarn`)
The number is required in only case of deploying YARN cluster for the shell.

> Key: FLINK-2935
> URL: https://issues.apache.org/jira/browse/FLINK-2935
> Project: Flink
> Issue Type: Improvement
> Components: Scala Shell
> Affects Versions: 0.9.1
> Reporter: Johannes
> Assignee: Chiwan Park
> Priority: Minor
> Labels: easyfix
>
> Currently the deployment of flink via yarn and the scala shell are not linked.
> When deploying a yarn session the file
> bq. org.apache.flink.client.CliFrontend
> creates a
> bq. .yarn-properties-$username
> file with the connection properties.
> There should be a way to have the scala shell automatically read this file if
> wanted as well.
