Jeff Hammerbacher commented on PIG-823:


Great to see Owl source! I've filed a ticket over on the Hive project 
(https://issues.apache.org/jira/browse/HIVE-762) to see if we can find some 
common ground between Pig and Hive's metadata needs; it would be great to have 
a single metadata service for all of Hadoop's structured data manipulation 
tools. If you're interested, please chime in there (or open a ticket here? 
Whatever seems sane to you).

> This JIRA is created to track development of a metadata system for  Hadoop. 
> The goal of the system is to allow users and applications to register data 
> stored on HDFS, search for the data available on HDFS, and associate metadata 
> such as schema, statistics, etc. with a particular data unit or a data set 
> stored on HDFS. The initial goal is to provide a fairly generic, low level 
> abstraction that any user or application on HDFS can use to store an retrieve 
> metadata. Over time a higher level abstractions closely tied to particular 
> applications or tools can be developed.
> Over time, it would make sense for the metadata service to become a 
> subproject within Hadoop. For now, the proposal is to make it a contrib to 
> Pig since Pig SQL is likely to be the first user of the system.
