I have received continuous Health Bad alert in cloudera manager for all hosts. It showing, "Network Interface Speed Unknown" error and It suppressed automatically after 2 minutes and saying Health is Good.
I am getting this alerts every 1 hour interval.
Also we already have the value of the 2 configuration parameters "Network Interface Expected Link Speed" as 1000 and "Network Interface Expected Duplex Mode" is Full.
I am in need the permanent fix on this issue.
Thanks,
Saravanan
