Jing Zhao commented on HDFS-8433:
---------------------------------
The issue with the changes on BlockTokenIdentifier's
serialization/deserialization is that it can break the compatibility between a
new NN and old DataNodes. Then during the rolling upgrade process, after we
upgrade the NN, the block token retrieved from the new NN cannot be parsed by
old DataNodes anymore, even if the token is actually for a non-striped block.
Therefore instead of the current solution, can we let NN return multiple block
tokens for a striped block group?
