Spring YARN and Hortonworks Sandbox
after much trial and error, here's some notes on getting Spring YARN to submit a remote job to Hortonworks sandbox...
- if working "remotely" (launching YARN job from one machine into the sandbox) make sure your local /etc/hosts is set to resolve sandbox.hortonworks.com on your target machine IP
- the ResourceManager port on HDP is 8050, not the default 8032 (spring.hadoop.resourceManagerPort: 8050)
- when running the job, use "HADOOP_USER_NAME=hdfs java -jar [your jar file]
