Tsz Wo Nicholas Sze commented on HDFS-6060:

Please also remove the DataNodeLayoutVersion import.  Patch looks good other than that.

> In current code, NameNode allows DataNode layout version to be different only when the
NameNode is in rolling upgrade mode. DataNode can't register with NameNode when only DataNode
is to be upgraded with a layout version different with that on NameNode.
> NameNode should not check DataNode layout version in any cases.
