Cannot run program "unzip" (in directory ".")

Hello,

I am running a cluster with one Nimbus and two supervisors. I got the
following error:

As explained on https://github.com/nathanmarz/storm/wiki/Setting-up-a-Storm-cluster, you need to have the unzip program installed and available on the cluster machines.

I have unzip installed. An env issue. Now I got the following errors.
I am calling Storm using absolute path "/apang/disk1/storm-0.7.0/bin/
storm supervisor". My jar file contain slf4j-log4j12-1.5.8.jar and
slf4j-api-1.5.8.jar from storm-starter. Should I delete the two jar
from storm-starter?

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/apang/disk1/storm-0.7.0/lib/slf4j-

What happens when you run "bin/storm supervisor" from within the /apang/disk1/storm-0.7.0 directory? Are you launching this from the command line or via another mechanism?
