Sean Busbey commented on HBASE-20594:
-------------------------------------
{code}
public TableDescriptorDelta(Set<byte[]> added, Set<byte[]> deleted, Set<byte[]>
modified) {
columnsAdded = ImmutableSet.copyOf(added);
columnsDeleted = ImmutableSet.copyOf(deleted);
columnsModified = ImmutableSet.copyOf(modified);
}
{code}
This constructor should be private, since we don't want downstream making their
own.
> provide utility to compare old and new descriptors

> HBASE-20567 gives us hooks that give both the old and new descriptor in
> pre/postModify* events, but comparing them is still cumbersome. We should
> provide users some kind of utility for this.
