Subject [jira] Commented: (PIG-823) Hadoop Metadata Service
Date Thu, 11 Jun 2009 09:37:12 GMT

    [ https://issues.apache.org/jira/browse/PIG-823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12718374#action_12718374

Matei Zaharia commented on PIG-823:
-----------------------------------

That sounds great. If this is sufficiently extensible, it might potentially even be useful
for data that is not in HDFS, such as HBase tables (though we should avoid making the system
overly complex).

> 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.
