> If a user issues a merge via the shell for a table with no other arguments, this causes
a table to merge down to one tablet. This can make Accumulo really unhappy, especially if
the number of files for that tablet exceeds the configured threshold (100 by default?).
> Perhaps a confirmation could be added to the merge command just to make sure that the
user knows what they are doing? Other ideas?
