Description

The MaaS service won't start with an stack trace:

{{java.lang.NoSuchMethodError: org.apache.hadoop.io.retry.RetryPolicies.retryOtherThanRemoteException(Lorg/apache/hadoop/io/retry/RetryPolicy;Ljava/util/Map;)Lorg/apache/hadoop/io/retry/RetryPolicy;

This is due to us packaging up yarn libraries with the maas service app rather than picking them up from Yarn.
