Subject [jira] [Commented] (HIVE-4621) "describe formatted" for table shows incorrect numRows data
Date Wed, 13 Nov 2013 02:47:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13820860#comment-13820860

Prasanth J commented on HIVE-4621:
----------------------------------

My understanding is that "LOAD DATA LOCAL" will never update statistics esp. numRows. This
is an expected behavior. The description says load data local is used so describe formatted
will always show numRows as 0.

> Created table (tab delimited), used "load data local" to get data into the table.
> After creating the table, "describe formatted" showed numRow as 0.
> select count(*) from... showed  43205 rows.
> Running "describe formatted" after "select count(*)" still shows numRows as 0.
