Xinyu Tan commented on IOTDB-5780:
----------------------------------
A procedure task is generated for cluster reduction. After all regions are
migrated, the system attempts to stop the corresponding node. During this
process, a log is printed for users to evaluate data migration.

In addition, you can run the show cluster command to view the status of the
region. We are still reconstructing these status types, which is expected to
take 1-2 months.
> Let users know a node was successfully removed and data is recovered

> When the datanode is removed, we will copy the data asynchronously to a new
> node to keep the replication_factor. Here users need to know how the
> asynchronous job is finished. We need to provide the inspection.
