Subject Passing Custom Arguments for giraph.zkList
Date Thu, 29 Aug 2013 21:05:50 GMT

I am trying to pass a zookeeper quorum to my giraph job and it throws the following exception:

13/08/29 13:14:38 INFO utils.ConfigurationUtils: No edge input format specified. Ensure your
InputFormat does not require one.
13/08/29 13:14:38 INFO utils.ConfigurationUtils: No output format specified. Ensure your OutputFormat

I pass the zklist like this:

Hadoop jar GRAPH.jar <CLASSNAME> -vip <CLASS NAME> -vif <CLASS NAME> -wc
<CLASS NAME> -w <worker number> -ca giraph.zkList="zk1:<port>,zk2:<port>,zk3:<port>,zk4:<port>,zk5:<port>"

Please suggest what is wrong with this invocation.
