Subject [jira] Commented: (HIVE-577) return correct comment of a column from ThriftHiveMetastore.Iface.get_fields
Date Mon, 29 Jun 2009 17:42:47 GMT

    [ https://issues.apache.org/jira/browse/HIVE-577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12725276#action_12725276
] 

Prasad Chakka commented on HIVE-577:
------------------------------------

this patch won't work for custom serdes where schema information stored in metastore is incorrect
or incomplete. eg, thrift serdes. correct way of doing this is to get the fields from Deserializer
and then look up the commet from the list in tbl.getSerDe().getCols().

> return correct comment of a column from ThriftHiveMetastore.Iface.get_fields
