It seems there was issue while electing active namenode as per last checkpoint.

To resolve this take both of the namenode down.

[Note:Before this you want to make sure which namenode has latest metadata.]

Start on of the namenode and make sure its performing fine. Then start the other namenode.

Let me know if the resolves the issue.

It seems like either one of the nodes is not updated with the correct status. Try restarting one of the Namenodes and check.

Hope this helps.

Thanks and Regards,

Sindhu
