Subject Re: Empty byte array values for cells which doesn't exist
Date Mon, 25 Sep 2017 04:36:26 GMT
Can you tell us more about this table (e.g. schema) ?

If you can formulate a unit test which reproduces this behavior, that would
be easier to debug.

Which version of hbase are you using ?

Cheers
