I'm able to submit a topology job in the multi-tenant cluster. The job is running. However, the logviewer page is not available. Is there any way to solve this issue? you need to start the logviewer before you click on topology port to see logviewer. To start logviewer run: $ storm logviewer same as you run $ storm list I faced the same issue for logviewer's home page, but directly navigating to a particular log file that exists in the logs folder works. Try this: MachineIP:8000/log?file=worker-6700.log 来源： https://stackoverflow.com/questions/25538327/storm-logviewer-page-not-found

I am having bit of an issue in logging to a file using log4j in storm . Before submitting my topology , i.e in my main method I wrote some log statements and configured the logger using : PropertyConfigurator.configure(myLog4jProperties) Now when I run my topology using my executable jar in eclipse - its working fine and log files are being created as supposed. OR When i run my executable jar using "java -jar MyJarFile someOtherOptions", i can see log4j being configured and the files are formed correctly and logging is done on both files and console (as defined in my log4j.properties) BUT when

What are the best practices, for building a multi-tenant app in the context of Kafka and storm? For example: creating topic for each tenant and consume multi-topics spout (using wildcard). I think that topic for each tenant is the right choice . The naming convention might be something like this: topic_base_name_tenant_id . The reasons are: It allows flexible configuration for each tenant (like @Sebastian mentioned earlier). Clearer logical separation. Now let's say that we will use different approach. For example, partition for each tenant. It might be problematic, since: You are limiting the
