Re: machine reboot

and assuming everything works fine (somehow it's not) I guess some assumptions above about Storm continues to work is wrong, what is the best practice or recommended way for our situation? Thanks, zainal From: rui.ab...@gmail.com At: 02/21/20 18:01:56To: Zainal Arifin (BLOOMBERG/ 731 LEX )

Re: machine reboot

Thanks Rui! Can I force the rebalance from a script? I am thinking to add in my current script, after it starts Storm, and checks if the topology is running. If yes, what would be the command or API? From: rui.ab...@gmail.com At: 02/21/20 16:48:53To: Zainal Arifin (BLOOMBERG/ 731 LEX

machine reboot

Hi, We run Storm on 2 machines (let's call it machine A and B), and everything works fine. Then I want to test the machine being reboot, so basically when the machine being brought down, it'll call my script to stop Storm, and when the machine back up, it called my script to start Storm. From m

using dns instead of machine names in nimbus.seeds

Hi, Will it work if I replace list of machines in nimbus.seeds config, with a single DNS name? I guess that won't work, but I want to check it first. Thanks!

question on deactivate and kill

Hi, Right now we have a bolt task that is in back log, i.e. ~10 hours behind processing the data. There was a bug and we have the fix which will speed up drastically. I think if I kill the topology (to deploy the fix), I will definitely lose those events been processed by the bolt, is that correc

Hi, I wonder if anyone who ever used streamparse (for storm topology in python code), ever run into this issue I am facing right now. Unfortunately, I don't see any error from streamparse log, but I see exception below in the storm worker log. The serializer exception section seems the culprit, b
