Hey Dipti - that error is normal - the script fires up a tmp zookeeper server to upload the conf files to. It then shuts that server down, which unfortunately logs this exception. Then the first Solr instance will run a zookeeper server. Uploading the configs ahead of time allows us to be sure the configs are certainly in zookeeper before the other servers start to come up. If you where doing it by hand, you could just pass the conf dir to the first Solr you started to upload the confs - then wait a second and start the other instances. Its done this other way in the script instead to eliminate any races.
