master server command shard problem

[leiwingqueen]

MasterSchedulerService responsible to scan the command table and dispatch the task to worker. if one master server down , other master server take the command instead.

//get command by slot
<select id="queryCommandPageBySlot" resultType="org.apache.dolphinscheduler.dao.entity.Command">
        select *
        from t_ds_command
        where id % #{masterCount} = #{thisMasterSlot}
        order by process_instance_priority, id asc
            limit #{limit} offset #{offset}
 </select>

other master will get notify from zookeeper and refresh the slot and masterCount. but the problem is that master server can not change those properties in the same time. Could it be a consistent problem?

or consistent hashing can solve the problem?
