[jira] Commented: (HADOOP-2041) Add convenience put method that takes writable

["Jim Kellerman (JIRA)" <ji...@apache.org>]

Jim Kellerman commented on HADOOP-2041:
---------------------------------------

Just to clarify the request, what I think you are proposing is adding:

public void put(long lockid, Text column, Writable val)

but you are not proposing to overload any of the get(...) methods or HScannerInterface.next
to return a Writable.

Overloading put is easy. Overloading get and next is hard because we currently do not store any type information for the value. All values are of type byte[]

If that is correct, then yes, we can add this in 0.16.0
