> Monitoring tools may choose to check liveness of the DataNode's data transfer
> port by connecting to it. The monitoring tool will close the connection
> immediately after establishment without sending any data. When this happens,
> the DataNode encounters an unexpected EOF and logs a full stack trace. This
> creates unneeded noise in the logs.
