elasticsearch version 7.6.2
I have installed mapper-size plugin on 3 nodes out of 5 I have in the cluster.
Restarting each node after the installation.
I have noticed that one index is going into RED status all the time sine installing the plugin.
So I have deleted the plugin from node-1 and everything got back to normal.
Also needed to close/open the indices manually, as some of them stayed in YELLOW status
Any known issues?
What can I do to avoid this situation? Or what to do when cluster health goes RED?
