zhuqi updated HBASE-25244: -------------------------- Description: In the current reference file format, only one parent region split into two references can be recorded.

If the reference file can point to other refenrence files, which data has not been moved from the parentRegion to the region under the corresponding folder, thereby establishing a multi-level reference. At this time, a tree structure is formed. Only the root contains physical data, and the region on the leaf node region is serving. was: In the current reference file format, only one parent region split into two references can be recorded.
