[jira] [Commented] (HIVE-10226) Column stats for Date columns not supported

    [ https://issues.apache.org/jira/browse/HIVE-10226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482151#comment-14482151 ] 

Gopal V commented on HIVE-10226:
--------------------------------

[~jdere]: Added to my daily build - does this change anything for the metastore?

Confirmed that the compute_stats() UDF gives me useful data for the column

But the stats are not getting saved as my metastore is throwing
