Anoop Sam John commented on HBASE-10885:
----------------------------------------
In 98.3 we allow the puts to have the vis exp in it. When a user issue delete,
it will delete all covered cells (irrespective of whether the put cells having
tags in it or not). This way it works till 98.3 Now in 98.4 we will change
this behavior. Is that okey?
> Support visibility expressions on Deletes

> Accumulo can specify visibility expressions for delete markers. During
> compaction the cells covered by the tombstone are determined in part by
> matching the visibility expression. This is useful for the use case of data
> set coalescing, where entries from multiple data sets carrying different
> labels are combined into one common large table. Later, a subset of entries
> can be conveniently removed using visibility expressions.
> Currently doing the same in HBase would only be possible with a custom
> coprocessor. Otherwise, a Delete will affect all cells covered by the
> tombstone regardless of any visibility expression scoping. This is correct
> behavior in that no data spill is possible, but certainly could be
> surprising, and is only meant to be transitional. We decided not to support
> visibility expressions on Deletes to control the complexity of the initial
> implementation.
