Running Storm on a Kerberized HDP 2.5.3 cluster and am able to run "storm list" to see no topologies are running and the Storm UI reports my two nimbus servers are running as well as my five supervisors. Now I'm getting the following excerpt when I tried to run the simple WordCount topology described in Step 4 on http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.3/bk_command-line-installation/content/validate_installation_storm.html.

I tried to increase the memory foot print of Nimbus from 1GB to 2GB and Supervisors from 768MB to 2GB with the changes highlighted below, but same error before and after this change. Did I make the right changes to give these services more memory?? Is there something else I should be trying?? ... View more
