Hualong Zhang updated HDFS-17052:
---------------------------------
Description:
When writing EC data, if the number of racks with DN that match the storageType
of the file is insufficient, multiple data blocks are allowed to be written to
the same rack.
However, during EC block recovery, it is not possible to recover on the same
rack, which deviates from the expected behavior.
