I ran Upgrade Assistant on my 5.6.3 ES cluster and I get an error that states:
Default path settings are removed
This issue must be resolved to upgrade. Read Documentation
Details: nodes with settings: [node1_data]
However I already have path.data and path.logs set in my elasticsearch.yml file:
\# grep ^path /etc/elasticsearch/elasticsearch.yml
path.data: /elasticsearch/data
path.repo: /elasticsearch/snapshots
path.logs: /elasticsearch/logs
These settings are identical on all my ES nodes.
Thanks,
Ryan
