> In CliFrontend#getClient() :
> {code}
>         yarnCluster = flinkYarnClient.deploy();
>         yarnCluster.connectToCluster();
> {code}
> Looking at FlinkYarnClientBase#deployInternal(), null return is possible:
> {code}
>     try {
>       org.apache.flink.core.fs.FileSystem.setDefaultScheme(flinkConfiguration);
>     } catch (IOException e) {
>       LOG.error("Error while setting the default " +
>         "filesystem scheme from configuration.", e);
>       return null;
>     }
> {code}
> We should check the return from deploy() before calling connectToCluster().
