Subject Re: Inserting different versions for a KeyValue through 2 HFiles while bulkloading
Date Tue, 16 Feb 2016 14:51:48 GMT
Hi Mehdi,

HBase wil sort the KeyValues based on the timestamp. So if you keep just
one version only the last one will be returned. If you keep more than one
and ask them all of them, then you will get both, ordered by timestamp.
