qinyuren updated HDFS-16432:
----------------------------
Description:
!image-2022-01-20-15-19-28-384.png|width=652,height=126!
In our cluster, namenode block report will held write lock for a long time if
the storage block number more than 100000. So we want to add a yield mechanism
in block reporting process to avoid holding write lock too long.
