Subject [jira] Commented: (HIVE-558) describe extended table/partition output is cryptic
Date Fri, 03 Sep 2010 18:53:33 GMT

    [ https://issues.apache.org/jira/browse/HIVE-558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12906015#action_12906015

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

Also, this change will break a lot of unit tests - have you had a chance to run the full suite?
In many unit tests, we do a describe extended that prints a single line with all the attributes.
The entire line was usually ignored as the location attribute had a 'file:/'.

With your change, we will now start comparing all the attributes, some of which which may
vary from run to run, e.g. table create time. Those attributes will need to be added to the
ignore list in QTestUtil.java:checkCliDriverResults()

> 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.
