I'm not sure of all the differences, but, wrt HBase Cell Level security
(CLS)..while similar..not 100% the same. If I understand how the HBase CLS
works it's extension to ACL system. And that ACL is "applied" to a cell.
In Accumulo's case, it is part of the key. So the ramification is that in
Accumulo, you can have:
RowID, CF, CQ, VIS1, TS --> Value1
RowID, CF, CQ, VIS2, TS --> Value2
If everything is the same, including the timestamp, the visibility can
actually determine which value to return. So, a more concrete example
XXX, METADATA, NAME, everyone, 100--> Bruce Wayne
XXX, METADATA, NAME, alfred-only, 100--> Batman
Where Alfred could/would see both "values"...but, everyone else would only
Hope that helps.
PS: this is my understanding of how HBase CLS works...based on what I have
