Re: Bolt slow down the emit speed of spout

Could you change your bolt to no-op but ack and run again? It makes your benchmark more clearer. And if you pick your number from the first 10 minutes, could you pick your number from another 10 minutes? It gets rid of worker / executor deploy / startup time, and warm-up of JVM. - Jungtaek Lim

Re: Is trident dead?

d out your own answer if no one interests your question (or no one can answer your question, who knows). Open source is not free, it requires time and efforts instead of money, and that's why open source technical support is valid for business model. Hope this helps to answer your question. T

Re: Storm-related interview on Linux.com

Nice interview, Julien! I think crawler is the interesting use case of Apache Storm which other declarative style streaming frameworks are hard to get. (I wrote the non-general one last year for internal project, too.) Hope that your session will be crowded. Thanks for sharing. - Jungtaek Lim

Re: Localcluster - ELK Bolt Example

You need to check the scope of storm-core. This needs to be set to 'compile' for running with local, and needs be set to 'provided' for running with remote cluster. 2016년 10월 13일 (목) 오후 5:16, Snabel Kabiya 님이 작성: > Hi Jungtaek Lim, > > > > Thank you, I’ve tr

Re: Cannot submit topology in local mode on Storm 1.0.1

Unfortunately without the minimal code which can reproduce this I'm hard to dig more. I followed the path based on stack trace, and it would be IllegalArgumentException, but it should have message which describes why it is thrown. Do you find more stack trace informations on that? - Jungtae

Re: Cannot submit topology in local mode on Storm 1.0.1

Hi Chen, Could you try running your topology with Storm 1.0.2 in local mode? Since it's in local mode you can easily try it out. Thanks, Jungtaek Lim (HeartSaVioR) 2016년 9월 20일 (화) 오후 5:26, Chen Junfeng 님이 작성: > My topology runs well in cluster mode but throws exceptions when it is >
