Hi Alejandro, I don't start all the AMs from the same JVM. How can I do that? Also, when I do that, that will save me time taken to get AM started, which is also good to see an improvement in. Please let me know how can I do that? And, would this also save me time taken for connecting from AM to the Resource Manager?
