Subject [jira] Commented: (HIVE-667) Provide hive ql to check table/partition status, including size, creation and access timestamp
Date Fri, 24 Jul 2009 04:18:15 GMT

    [ https://issues.apache.org/jira/browse/HIVE-667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12734896#action_12734896

Hao Liu commented on HIVE-667:
------------------------------

"Describe extended" provides some static metadata informatio. But for those table info like
size and access/update time, one needs to contact hdfs (or whatever storage layer hive use).
I am thinking in terms of implementation, hive clik can provides this function? It can be
part of metastore function though, which will work, but not necessary though if we want to
decouple metastore and hdfs.
My sql provide similar function:

> Those information will be helpful both for data management tasks, and users who send
adhoc queries against big data set in the cluster. .
