The YARN Application Master for Giraph is launched when the GiraphYarnClient successfully requests an execution container from the Resource Manager.
The initial launcher for a YARN-based Giraph job.
|GiraphYarnTask<I extends org.apache.hadoop.io.WritableComparable,V extends org.apache.hadoop.io.Writable,E extends org.apache.hadoop.io.Writable>
This process will execute the BSP graph tasks alloted to this YARN execution container.
Utilities that can only compile with versions of Hadoop that support YARN, so they live here instead of o.a.g.utils package.
