Hadoop Metadata Service

                 Key: PIG-823
                 URL: https://issues.apache.org/jira/browse/PIG-823
             Project: Pig
          Issue Type: New Feature
            Reporter: Olga Natkovich

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.
