@Nicola Marangoni @David Tam @Breandán Mac Parland Oozie Spark action is not supported in HDP 2.4 or earlier. There are workarounds on this site you may find but they're not supported by Hortonworks. This means you can get it to work but you can't open tickets in regards to them with our support. Can you set jobTracker to port 8032 instead of 8050 and try again? Look at this question as it's similar https://community.hortonworks.com/questions/11599/how-to-change-resourcemanager-port-on-oozie.html#answer-21336 Hortonworks uses the source code from Apache Oozie and internally Apache Oozie version expects port 8032 for yarn.resourcemanager.address not 8050. Look at the unit test example https://github.com/apache/oozie/search?utf8=%E2%9C%93&q=8032 in our private repos, this is an identical unit test. You guys all have similar questions, I will raise an internal discussion on how to proceed with this.
