Subject [jira] Commented: (HIVE-577) return correct comment of a column from ThriftHiveMetastore.Iface.get_fields
Date Tue, 30 Jun 2009 20:42:47 GMT

    [ https://issues.apache.org/jira/browse/HIVE-577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12725797#action_12725797

Raghotham Murthy commented on HIVE-577:

Check HIVE-590. We are going to fix Driver.getSchema() to return a structure rather than return
a string which needs to be parsed again in the client. 

I am wondering if we can get rid of duplicate logic of getting schema of table or query result
in HiveMetaStore vs Driver. I couldnt find any place (other than thrift generated code) where
we call get_fields(). So, do we really need this method at all given that Driver will provide
this functionality?

Regarding this patch, can you add a test?
