Lars Hofhansl commented on HBASE-3584:
--------------------------------------
At a computer now. Stack you're right RowMutation of HBASE-3967 encapsulates
either a Put or a Delete.
In trunk we have Mutation now as common superclass to Put and Delete, that
class should be used to indicate either Put or Delete (the way I did it in
HBASE-4682):
{code}
static class Importer
- extends TableMapper<ImmutableBytesWritable, Put> {
+ extends TableMapper<ImmutableBytesWritable, Mutation> {
private Map<byte[], byte[]> cfRenameMap;
{code}
I think this gets very confusing. We have Mutation as superclass of Put and
Delete, RowMutation to be either a Delete or a Put, and RowMutations, which is
a grouping of operations for the same Row.
Kannan, can you use Mutation.java from trunk for the MR jobs they way I did in
HBASE-4682?

> Right now we have the following calls:
> put(Put)
> delete(Delete)
> increment(Increments)
> But we cannot combine all of the above in a single call, complete with a
> single row lock. It would be nice to do that.
> It would also allow us to do a CAS where we could do a put/increment if the
> check succeeded.

> Amendment:
> Since Increment does not currently support MVCC it cannot be included in an
> atomic operation.
> So this for Put and Delete only.
