Answer 1

It seems that to port is not free. Make sure no other process/service uses the port or reconfigure Storm to use a different port.
In order to change the port, you need to edit conf/storm.yaml file (best on each machine that runs a supervisor). Do compare with defaults.yaml in order to find the correct parameter name.
The second error seems to relate to the local Storm tmp directory. Try to shut down the cluster, clear this directory, and restart Storm.
