Issue:
Cluster pipelines failing with an exception "Timed out after waiting 121 seconds for for cluster application to start."
Solution:
This is a very generic message and the only information it provides is that the pipeline was not able to start. For further troubleshooting, it is helpful to look into the sdc.log file and the yarn logs for that particular application ID.
