--------------------------------

             Summary: change max_deduplicated_path_num does not take effect
                 Key: IOTDB-2533
                 URL: https://issues.apache.org/jira/browse/IOTDB-2533
             Project: Apache IoTDB
          Issue Type: Bug
          Components: Core/Query
            Reporter: Yuan Tian
            Assignee: Yuan Tian


If we change meta_data_cache_enable=false and change max_deduplicated_path_num in iotdb-engine.properties meanwhile, max_deduplicated_path_num won't take effect.

 

Change the following two items in iotdb-engine.properties

```

meta_data_cache_enable=false

max_deduplicated_path_num=2

```

And then start iotdb-server.

And then execute the following commands

```

insert into root.sg.d1(time,s1) values(1,1);

insert into root.sg.d1(time,s2) values(1,1);

insert into root.sg.d1(time,s3) values(1,1);

select last s1, s2, s3 from root.sg.d1;

```

We expect to get `PathNumOverLimitException: Too many paths in one query!` exeception, because we already change max_deduplicated_path_num to 2, but it can be executed successfully.
