Hello All, I was able to get around the issue pasted above by manually copying the javaee-api-7.0 jar inside the lib folder of Apex engine. It may be noted that the code works perfectly fine in a unit test that launches all of the operators in the DAG. ( Works end to end ) . However when I launch it on CDH 5.7 I run into the exception pasted above. It may be noted that the exception is being raised when I launch the app and the Apex engine is trying to validate the newly deployed app.
I am suspecting that this could be an issue with incompatibility with CDH 5.7 ( The Hadoop stack on which I am trying to run Apex 3.3 on ) Could anyone help me if they were able to run Apex on top of CDH 5.7. I got the same exception with both Apex 3.3 and 3.2.
