[jira] [Updated] (STORM-484) Implement topology validation logic in TopologyBuilder

     [ https://issues.apache.org/jira/browse/STORM-484?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Brailsford updated STORM-484:
-------------------------------------
    Description: Currently topology validation occurs only when submitting the topology to nimbus.  Once a topology is built with TopologyBuilder.createTopology() all relevant data to validate a topology is correctly wired already exists.  However, TopologyBuilder.createTopology() incurs the cost of serializing the ComponentObject which isn't needed to validate the topology is wired correctly.  The operation of validating a topology can provided in TopologyBuilder, or a helper class like TopologyValidator, to validate a topology while it is being built by consumers without the cost of serializing ComponentObjects or submitting to nimbus.
