I'm working on a marathon hosted cluster (7.6.2) which is not very stable sometimes.
Occasionnaly when there is a host failure, I end up with the following on a data node :
java.lang.IllegalStateException: no global metadata found in [/usr/share/elasticsearch/data/nodes/0]
I found very little info, and especially I have found NO mention of such a problem in here.
When I google this specific message, only ES sources show up.
Where/how exactly is stored global metadata ?
Is there someting I can do besides resetting the node and losing data ?
Please let me know if you need more context or anything,
and thanks in advance for your answers !
