Hi @HS, Thank you for your comment on our Metron documentation. Sorry the delay in responding to you. I've raised your question to the Dev team and I hope to have an answer for you shortly.

I am working on adding a Squid telemetry to an Ambari-managed cluster on AWS. I've parsed and transformed the Squid message, but I am getting the following error message when I attempt to push it to Zookeeper: [root@ip-10-0-0-90 ~]# /usr/metron/0.2.0BETA/bin/zk_load_configs.sh -i /usr/metron/0.2.0BETA/config/zookeeper -m PUSH -z ec2-xx-xx-xxx-xxx.us-west-2.compute.amazonaws.com:2181 log4j:WARN No appenders could be found for logger (org.apache.curator.framework.imps.CuratorFrameworkImpl). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info. I checked the referenced Apache FAQ and found the following answer: Why do I see a warning about "No appenders found for logger" and "Please configure log4j properly"? This occurs when the default configuration files log4j.properties and log4j.xml can not be found and the application performs no explicit configuration. log4j uses Thread.getContextClassLoader().getResource() to locate the default configuration files and does not directly check the file system. Knowing the appropriate location to place log4j.properties or log4j.xml requires understanding the search strategy of the class loader in use. log4j does not provide a default configuration since output to the console or to the file system may be prohibited in some environments.
Not quite sure how to resolve this. Any help would be appreciated. Thanks!

@apsaltis After some research I discovered the easiest way to ensure that Squid is assigned a worker is to kill one or more of the existing topologies. The Storm Supervisor will then assign one of the free workers to Squid. You can kill a topology either in the Storm UI or in the CLI. I will add a step to cover this in the article. Thanks again for your comments.

@Rob Becker How did you resolve this issue? Someone suggested either deactivating or killing another of the topologies to free up a worker. I tried both and neither works. Did you add another port? If so, how? Thanks for your help.

@apsaltis , Thanks for your comment. I believe you're correct and we need an additional step to add a port. I'm researching the best way to add that port and I will modify that step when I have my results. Thanks for your help.

@apsaltis I'm modifying my previous reply. To deploy the new squid parser topology, you do not need to use "sudo" anywhere except at the very beginning of the command string. I tried it twice as is and it worked perfectly both times. Thank you for your feedback though. We really appreciate you taking the time to comment on the instructions so we can improve them.

@apsaltis When I downloaded the tar file it was named "incubator-metron-codelab-v1.0.tar.gz" which means the example to untar the file should be correct. Would you please check your download again to confirm that it is named "codelab-v1.0.tar.gz". Thanks!
