Lars Hofhansl commented on HBASE-5670:
--------------------------------------

Thanks Stack.
Since you can pass List<Row> to a method that takes List<? extends Row> it'll work without the need to recompile anything.
The client<->server communication is done via HConnection.processBatch, which is public and actually already takes List<? extends Row>. Seems the List<Row> interface in HTable was just an oversight.

> In HBASE-4347 I factored some code from Put/Delete/Append in Mutation.
> In a discussion with a co-worker I noticed that Put/Delete/Append still implement the Row interface, but Mutation does not.
> In a trivial change I would like to move that interface up to Mutation, along with changing HTable.batch(List<Row>) to HTable.batch(List<? extends Row>) (HConnection.processBatch takes List<? extends Row> already anyway), so that HTable.batch can be used with a list of Mutations.
