Hrishikesh Gadre commented on HDDS-1201:
----------------------------------------
[~arpitagarwal] / [~sdeka] I have been looking into this. On the HDFS side, DN
reports corrupted blocks as a separate RPC request (as against adding it in the
block report itself). Do we want to have similar implementation on Ozone? I
wonder if it would be better to include this info in the block report itself?
Any thoughts?
Here are some pointers in the HDFS code,
