Subject [jira] [Commented] (HIVE-9480) Implement FIRST_DAY as compared with LAST_DAY already supported in HIVE
Date Tue, 27 Jan 2015 22:30:34 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14294315#comment-14294315

Xiaobing Zhou commented on HIVE-9480:
-------------------------------------

Since most of logic for FIRST_DAY and LAST_DAY are common. It'd be better to reuse LAST_DAY
impl and make some abstractions to simplify FIRST_DAY impl.

> Hive already supports LAST_DAY UDF, in some cases, FIRST_DAY is necessary to do date/timestamp
related computation. This JIRA is to track such an implementation.
