Chenyu Zheng updated HDFS-17550:
--------------------------------
Description:
By enabling reconstruction to decommissioning datanode, the speed increased by
12 times on a small-scale cluster with only 100 machines dedicated to storing
EC data. I think in prodcution cluster with thousands of clusters, there will
be hundreds of times growth.
I will submit PR after HDFS-17542
