Subject [jira] [Created] (ACCUMULO-1744) A "smarter" merge command
Date Tue, 01 Oct 2013 03:45:32 GMT
Josh Elser created ACCUMULO-1744:

             Summary: A "smarter" merge command
                 Key: ACCUMULO-1744
             Project: Accumulo
          Issue Type: Improvement
          Components: shell
            Reporter: Josh Elser
             Fix For: 1.7.0

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.
