Subject [jira] [Updated] (HIVE-8648) numRows cannot be set by user
Date Thu, 30 Oct 2014 01:22:34 GMT

     [ https://issues.apache.org/jira/browse/HIVE-8648?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brock Noland updated HIVE-8648:
-------------------------------
    Description: 
Since HIVE-3777 users who want to set the number of rows for a table, must do as follows:

{noformat}
alter table ... set tblproperties ('numRows' = '12345', 'STATS_GENERATED_VIA_STATS_TASK' =
'true');
{noformat}

Which is strange because (1) users can know the numbers of rows and (2) the stat is not generated
by a stats task.

  was:
Since HIVE-3777 users who know the number of rows in a table and want to set that statistic
must do:

{noformat}
alter table ... set tblproperties ('numRows' = '12345', 'STATS_GENERATED_VIA_STATS_TASK' =
'true');
{noformat}

Users should be able to set the number of rows.
