Hi,
I have a similar problem. Ive defined complete write permission for my
folder that Ive defined in data.path: /var/lib/elasticsearch/elasticsearch
I still get the error Failed to obtain node lock, is the following location
writable?: [/var/lib/elasticsearch/elasticsearch]
Could you tell me where I`m doing wrong??
