P.S., the attachment you post w/ the previous email does not show up (Apache mailing list disallow attachments). If would be better if you send the command line outputs in pure text or html format. -Yi On Thu, Sep 14, 2017 at 3:34 PM, Yi Pan wrote: > Hi, Anantharaman, > > A lot of firewall setu

I wonder if this has anything to do with previous kafka / zookeeper installed on your box. Just for sanity, try clearing /tmp/zookeeeper* and /tmp/kafka* before re-trying those steps. Same as Yi, I strongly suspect issues with your local laptop setup - it could either related resolving "localh

Hi, Anantharaman, I just did the same steps as you described in your email and all passed on my box. Hence, I strongly suspect that it is related to your local laptop network setup. Could you post all the command line output when you ran the sequence of commands? -Yi On Thu, Sep 14, 2017 at 11:

Hi Yi, Thanks for all the suggestions. Our team eventually decided to move off CDH Kafka(and YARN) due to some issues not relevant to Samza. For what its worth, I did test the a couple basic Hello Samza (Samza 0.13.1) jobs against a single node CDH Kafka version 0.10.2.0+kafka2.2.0+110 with succes
