I tried to run the note book demo available on Zeppelin in Hortonworks sandbox 2.4 (Notebook named twitter) to learn SparkStreaming. According the instruction on the top of notebook (/* BEFORE START....), I logged on Ambari to modify the configuration of Yarn service.
CPU => Container: Minimum Container Size (VCores) 4; Maximum Container Size (Vcores): 8
Memory
Node: 2250MB
Container: Minimum Container Size: 768MB; Maximum Container Size: 2250MB
All services are restarted after modifying but when I came back to Zeppelin to run the notebook, the second paragraph (/* UPDATE YOUR TWITTER CREDENTIALS */....) was always on the state "running" but never "finished". All twitter credentials are already updated.
P/S: without modifying the YARN configuration, I could run the second paragraph, but when running the 3rd, It was always "running" but never "finished"
Thanks for any suggestions
