Standalone Tests

Slider core contains a suite of tests that are designed to run on the local machine, using Apache Hadoop's MiniDFSCluster and MiniYARNCluster classes to create small, one-node test clusters. All the YARN/HDFS code runs in the JUnit process; the AM and spawned processes run independently.
