Camus not completing

[Stephen Rausch]

Hello.  I am trying to get write to a hdfs using Camus.  When I run: ./bin/camus-run -D schema.registry.url=http://localhost:8081 -P etc/camus/camus.properties I get the following output.

SLF4J: Class path contains multiple SLF4J bindings.

I would certainly appreciate any thoughts on this.  Thank you

This looks like an issue with your HDFS cluster, apparently there are no data nodes available. I would suggest investigating with the administrator of the cluster, or if you set it up, it is likely that it was configured incorrectly. The relevant error is:

File /user/username/exec/2015-12-15-18-09-12/requests.previous could only be replicated to 0 nodes instead of minReplication (=1).  There are 0 datanode(s) running and no node(s) are excluded in this operation.

I was able to get it running properly after a hardware restart and a namenode format.  The datanode was not starting properly.  Thank you.
