#Hi all,

when i tried to run the logging aggregation following your video on youtube , i found out the following error generated by elasticsearch:

BTW i am running a kubernetes cluster v1.8.0 on minions and 1.9.0 on masters using cri-containerd on Ubuntu machines 16.04.

any help will be appreciated
