I tried the following two suggestions independently (full restarts of Zeppelin each time) with no luck. First, via Ambari, I changed zeppelin.executor.mem from 512m to 256m and zeppelin.executor.instances from 2 to 1. Then, again via Ambari, I updated the following snippet of the zeppelin_env_content from export ZEPPELIN_JAVA_OPTS="-Dhdp.version={{full_stack_version}} -Dspark.executor.memory={{executor_mem}} -Dspark.executor.instances={{executor_instances}} -Dspark.yarn.queue={{spark_queue}}" to export ZEPPELIN_JAVA_OPTS="-Dhdp.version={{full_stack_version}} -Dspark.executor.memory=512m -Dspark.executor.instances=2 -Dspark.yarn.queue={{spark_queue}}" Both times, my little 2.5 Sandbox was still running full throttle once I run some code in Zeppelin. If anyone notices what I missed on this, please advise. ... View more

Instructions for this are in the course lab guide (step 7 of lab 1). For benefit of all, I stripped out just those pages and am attaching the steps as jpegs. ... View more

Hey @Rafael Coss, I am not crazy, this is supposed to work in the Sandbox, right? Not the end of the world if it isn't, just didn't want to miss out if I'm just overlooking a small activity. ... View more

Good write-up from @Ambud Sharma plus you can visit http://storm.apache.org/releases/1.0.2/Guaranteeing-message-processing.html for info from the source. Additionally, take a peek at the picture below I just exported from our http://hortonworks.com/training/class/hdp-developer-storm-and-trident-fundamentals/ course that might help visualize all of this information. Good luck and happy Storming! ... View more
