what is the working directory for jar laucher in apache storm topology jar

Question

I am a novice in Apache Storm. I have created a storm project in java and it successfully creates. My Application had a java process which needs absolute path of the application working directory or class path of the topology jar. please answer my following question:

1. What is the path of the class files of a topology jar which we upload using storm jar command ?

2. I am java process which need some JVM parameters, i had tried setting them in storm.yaml file. Is it right way to do or not ?

Answer 1

The uploaded jars go into {storm.local.dir}/nimbus/inbox (or something similar -- can't remember exactly). storm.local.dir is configured in storm.yaml .

Using worker.childopts in storm.yaml to set worker JVM options is the correct way to go.

Answer 2

After trying different type of use cases and options available in internet, i found solution to my problem.

Using topology.classpath in topology Config to set the classpath of the jars i want to read its working.
