Description

presently truncate on disabled table is deleting existing table and recreating(ENABLED)
disable(table_name) call in truncate returing if table is disabled without nofifying to user.

    def disable(table_name)
      tableExists(table_name)
      return if disabled?(table_name)
      @admin.disableTable(table_name)
    end

one more thing is we are calling tableExists in disable(table_name) as well as drop(table_name) which is un necessary.
Any way below HTable object creation will check whether table exists or not.

h_table = org.apache.hadoop.hbase.client.HTable.new(conf, table_name)

We can change it to

      h_table = org.apache.hadoop.hbase.client.HTable.new(conf, table_name)
      table_description = h_table.getTableDescriptor()
      yield 'Disabling table...' if block_given?
      @admin.disableTable(table_name)

      yield 'Dropping table...' if block_given?
      @admin.deleteTable(table_name)

      yield 'Creating table...' if block_given?
      @admin.createTable(table_description)
