Hi @harshach , the main reasons we change log location are two-fold: 1) we
want to separate the daemon logs from worker logs for better namespace and
permission management; 2) the workers-artifacts directory are beyond "just
logs", it appears more like a drop-box for each worker, containing log files,
heapdump, gc files, and other possible files users may need to dump.
It will be one line change to "config/worker-artifacts-root" function if we
want to place worker-artifacts under storm-home/logs/. In that way it will look
as follows. In our opinion, it would be preferable to let workers-artifacts to
stay with storm-local/workers, worker-users.
We can discuss which one is more appropriate.
storm-home/logs/
------supervisor.log
------nimbus.log
------workers-artifacts/
-----------topo1/
------------------port1/
------------------port2/
------------------------worker.log
------------------------worker.log.err
------------------------gc.log
