Subject Re: Duplicate Value Inserts in HBase
Date Tue, 21 Oct 2014 12:50:05 GMT
Thanks Jean,
If i put the same value in my table for a particular column for a rowkey i
want HBase reject this value and retain old value with old time stamp.
In other words update only when value changes.

Regards,
Krishna
