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.
> Hive should return the latest hbase cell timestamp as the row timestamp value

> 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.
