Yukun Zhou commented on IOTDB-5045:
-----------------------------------
Please check when executing the script provided, does the cluster still
receiving other requests from some clients. The operation in the scripts seems
unable to create such large region id range (6~50).
> [delete] After running "drop database root.**", wal and tsfile still left

> [delete] After running "drop database root.**", wal and tsfile left rather
> than cleanup
> 3C3D cluster, Nov.25 14:00 source codes
> reproduction:
> execute the statements of attchachment udf-privilege.run on start-cli.sh
> window several times
> actual result:
> They are all empty:
> show databases;
> show timeseries root.**;
> show regions;
> I've run flush in command wiindow but no use.
> But there are also tsfile and wal files left and won't be removed.

> 另外：
> 反复创建同一名称的aligned和nonAligned timeseries 并插入数据然后drop database root.**, 可能会导致
> root.sg1 在show regions时有成倍的dataregion。
