Flink 1.10 classpath

[Richard Moorhead]

We're submitting jobs to a flink session running on YARN. Our yarn-site.xml
does not have our mapreduce libs in yarn.application.classpath. Our
application code has some provided dependencies from
hadoop-mapreduce-client-core. Without editing our yarn-site, or adding
those libraries to the flink lib dir, how can we extend our session's
classpath?
