Subject [jira] [Commented] (HIVE-12635) Hive should return the latest hbase cell timestamp as the row timestamp value
Date Fri, 11 Dec 2015 15:06:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15052869#comment-15052869

Aihua Xu commented on HIVE-12635:
---------------------------------

1. Timestamp variable can be negative. One way is to init it to LONG.MIN_VALUE, but I thought
the current way is kind of the same. Somehow trying to avoid init to MIN_VALUE. :) Let me
know if you want me to make that change.

2. Yeah. You are right. It will be backward-imcompatibility. I will mark that.

> When hive talks to hbase and maps hbase timestamp field to one hive column,  seems hive
returns the first cell timestamp instead of the latest one as the timestamp value. 
> Makes sense to return the latest timestamp since adding the latest cell can be  considered
an update to the row.
