Subject [jira] Commented: (HIVE-558) describe extended table/partition output is cryptic
Date Mon, 30 Aug 2010 22:13:55 GMT

    [ https://issues.apache.org/jira/browse/HIVE-558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12904371#action_12904371
] 

Paul Yang commented on HIVE-558:
--------------------------------

Looks pretty good but in DDLTask, the updated code does not make use of field List<FieldSchema>
cols and instead just relies on the table object. Since cols could have been formed via Hive.getFieldsFromDeserializer()
(DDLTask.java 1553) your change might give different results.

Also in formatOutput(), why is the field width 15 in one instance but 20 for the rest? Also,
could you move the width to a static constant?

> describe extended table prints out the Thrift metadata object directly. The information
from it is not easy to read or parse. Output should be easily read and can be simple parsed
to get table location etc by programs.
