how to split app log from worker log?

[Edison <xe...@gmail.com>]

Hi,

I'm trying to print my own log information using slf4j api into a seperated
log file, e.g. test.log from worker-xxxx.log.
I tried to configure the cluster.xml to add a new appender to set the
test.log, and a new logger for invocation. But it's not working.

At the end, I found a workaround that using logback JoranConfigurator to
point to a seperate logback.xml to replace the default one, it's working. I
got my app log there. But the thing is, new logback configuration will
overwrite storm's, thus storms' output are gone.

Is there a good way to impl it?

Thank you
