Get the splits of the named table:
  hbase> get_splits 't1'
  hbase> get_splits 'ns1:t1'

The same commands also can be run on a table reference. Suppose you had a reference
t to table 't1', the corresponding command would be:

  hbase> t.get_splits
EOF
      end

      def command(table)
        get_splits(table(table))

                    numsplits: (splits.size + 1)))
