zhuqi updated HBASE-25244:
--------------------------
Description:
In the current reference file format, only one parent region split into two
references can be recorded. At this time, if you want to continue splitting the
daughter region, you must wait until the majorCompaction is over and the
reference file is deleted before you can continue to split the region.
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.
