   ### Search before asking
   
   - [X] I had searched in the 
[issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and 
found no similar issues.
   
   
   ### Description
   
   Sometimes, I want to know the order of tablet (AKA bucket sequence of 
tablet) of a colocation table. So that I can find the Backends list assigned to 
this bucket.
   
   ### Use case
   
   ```
   mysql> show tablet 126684560\G
   *************************** 1. row ***************************
          DbName: default_cluster:db1
       TableName: tbl1
   PartitionName: partition1
       IndexName: tbl1
            DbId: 1501243
         TableId: 59019459
     PartitionId: 59019458
         IndexId: 126684539
          IsSync: true
           Order: 5
       DetailCmd: SHOW PROC 
'/dbs/1501243/59019459/partitions/59019458/126684539/126684560';
   ```
   
   And now I know the order of this tablet is `5`. Than I can find backend 
lists of this bucket by:
   
   ```
   mysql> show proc "/colocation_group/61190005.97437015";                      
                                                                                
                                               
+-------------+------------------------------+
   | BucketIndex | {"location" : "default"}     |
   +-------------+------------------------------+
   | 0           | 65109230, 63737443, 65108975 |
   | 1           | 63737443, 65108975, 65102017 |
   | 2           | 63737443, 65108975, 65102017 |
   | 3           | 63737443, 65108975, 65109230 |
   | 4           | 65102017, 63737443, 65109230 |
   | 5           | 65102017, 63737443, 65108975 |
   | 6           | 63737443, 65109230, 65108975 |
   ```
   
   The backend list of bucket 5 is `65102017, 63737443, 65108975`
