Keith Turner commented on ACCUMULO-1744:
----------------------------------------

The merge command in the shell has the size option.  Is this what you are looking for?

> The `merge` shell command is a nice little feature that helps undo bad partitioning of
a table due to a variety of reasons (too many splits added, too small of a split threshold).
> The way that `merge` actually works isn't very user friendly as it forces the user to
manually chain invocations of `merge` together to "implement" the semantics they really want
of merge into N tablets or merge into tablets of size no more than X.
> Given that we have all of the information stored in {{!METADATA}} to atuomatically compute
this, it seems like a straightforward command that we could provide, whether as different
options on the existing `merge` command or as a new command.
