[jira] [Commented] (STORM-22) Expose stream metadata via TridentOperationContexts

    [ https://issues.apache.org/jira/browse/STORM-22?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14004541#comment-14004541 ] 

Simon Cooper commented on STORM-22:
-----------------------------------

It would also be useful to have access to the underlying TopologyContext object to get things like the storm component id, worker port & machine the operation is running on for reporting and debugging purposes.
