A cluster is like this:
A single namenode
A secondarynamenode
Three datanode
Log shows the namenode and datanode different CID
Checked that modify the datanode CID for the namenode,
But I don't know where is the change,
I'm five computer datanodedate folder VERSION of CID is a
The namenode host of namenodedata folder VERSION of CID is b
The rest of the four machine namenodedata folder VERSION of CID is a,
Which is now to change computer which folder under the CID? Saw many articles which didn't make it clear to ID, hope to help bosses

This reason is caused by multiple format, you can delete the data folder to reformat it again

to see if the time is not synchronous

thank you for your answer, have solved, and it was a small white, time synchronization problem although I did not use the NTP, but time of the cluster is the same,
