> We found that transfer block failed during the namenode upgrade. The specific
> error reported was that the block token verification failed. The reason is
> that during the datanode transfer block process, the source datanode uses its
> own generated block token, and the keyid comes from ANN or SBN. However,
> because the newly upgraded NN has just been started, the keyid owned by the
> source datanode may not be owned by the target datanode, so the write fails.
> Here's how to reproduce this situation in the attachment
