Hi, I am working with a client that uses Informatica Metadata Manager to visualise Lineage Information. Informatica Metadata Manager is currently used at Data Warehouse layer and is proven effective. But unfortunately Informatica Metadata Manage does not have any connectors to Hadoop to collect metadata information, which makes it not so desirable tool for the entire end to end chain. This is where Apache Falcon comes to the rescue.
Looking at Falcon, I see that Falcon exposes a set of REST APIs that can be used to capture metadata information about process,feed and cluster entities (assuming that the workflow is scheduled using Apache Falcon). So we are exploring option on how we can actually generate metadata at Hadoop layer that can then be used to feed informatica Metadata Manager, which will combine it with its own metadata from DWH and Business reports to provide a complete Lineage information. I have three specific question with regard to the above problem : 1. Where is the Metadata Repository located for Apache Falcon? Is it the config store on Hadoop or Hcatalog ? 2. Is there a way to connect to this repository(for e.g.. via JDBC) ? 3. What set of REST APIs can be called from outside of the Falcon environment to capture the Metadata Information about the processes scheduled using Falcon ? I looked at these<http://falcon.apache.org/0.6.1/restapi/> set of REST APIs, which was a start for me, but I got lost in the details. Your quick answer would be really appreciated.
