-
-To work the collection worker need some parameter like:
-
-* **hdfsPath**: the path where storing the sequential file
-* **apidescriptor**: the JSON encoding of the API Descriptor
-* **namenode**: the Name Node URI
-* **userHDFS**: the user wich create the hdfs seq file
-* **rabbitUser**: the user to connect with RabbitMq for messaging
-* **rabbitPassWord**: the password to connect with RabbitMq for messaging
-* **rabbitHost**: the host of the RabbitMq server
-* **rabbitOngoingQueue**: the name of the ongoing queue
-* **rabbitReportQueue**: the name of the report queue
-* **workflowId**: the identifier of the dnet Workflow
