Hello,
lately I noticed some network frame errors on some hosts. The server are bare metal hosts and we already tried to upgrade the firmware for the network interfaces and change the patch-cords, but it didn’t helped. The errors are visible for both eth interfaces that we have in our servers.
The errors causing the instability of the Cloudera cluster and services timeout. Can someone help with this issue?
