[jira] [Commented] (SAMZA-1304) Improve duplicate processors detection

    [ https://issues.apache.org/jira/browse/SAMZA-1304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16020027#comment-16020027 ] 

Boris Shkolnik commented on SAMZA-1304:
---------------------------------------

Duplicate - you mean with the same processor ID?
I think writing to ZK is the only way to find it out. Do you have any other suggestions?

> In current implementation, duplicate processors are detected during write to the ZooKeeper. 
> Expensive JobModel generation and Zookeeper write could be avoided, if duplicate processorIds are checked for in StreamProcessor that is Leader.
