[jira] Commented: (HIVE-577) return correct comment of a column from ThriftHiveMetastore.Iface.get_fields

["Prasad Chakka (JIRA)" <ji...@apache.org>]

    [ 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().
