Subject [jira] Created: (PIG-823) Hadoop Metadata Service
Date Fri, 29 May 2009 17:58:45 GMT
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.
