We had a problem on a new installation where mapr was complaining about unable to find RpcProgram.  We did uninstalls and reinstalls of everything and continued to have the problem.  Ultimately, we deleted everything in Zookeeper (while all the cluster components were shutdown) and then brought the cluster back up.  Everything then worked fine (no more Rpc complaints).  This cluster didn't have anything in it yet so we felt fine doing this.  In the future, would this cause any problems?  Is there any information stored in zookeeper which cannot be repopulated by the cluster?
