"org.apache.storm" % "storm-kafka-client" % "1.2.1"
With this version of storm, when running topology, I see two processes for
each worker: one for logwriter and other for worker, as mentioned here
<https://stackoverflow.com/a/42517250/1610034> as well.
The problem is I want to give less memory to logwriter process(say
-Xmx512mb) and higher to worker process(say -Xmx12gb). But I am not able to
achieve this, I have tried playing with different config.
There is config topology.worker.logwriter.childopts, which is taken by
logwriter process, but than I have given some config to worker.childopts ,
but that also gets applied to both logwriter and worker process. Similary I
tried using topology.worker.childopts and that also gets applied to both
logwriter and worker process.
How to solve this to give lesser memory for logwriter process and higher
for worker process?
