Hi All,
Recently had to migrate a 2-node elasticsearch cluster from old (old_machine_1, old_machine_2) to new servers(new_machine_1,new_machine_2). The data directories (~55GB each) was copied between the 2 sets of machines.
old_machine_1 => new_machine_1
old_machine_2 => new_machine_2
Elasticsearch version(1.6.1) remains the same on the new servers .
After elasticsearch is started on the new machines, queries fail with "IllegalStateException: Field data loading is forbidden on Field1" .
The following properties were changed in elasticsearch.yml when elasticsearch moved to the new servers
- node.name :
- path.data: pointing to the directory where data was copied
- discovery.zen.ping.unicast.hosts: <new_machine_1>, <new_machine_2>
Was anything missed that caused this error ?
What can be done to fix the issue ?
Appreciate your inputs.
