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

1. node.name : 
2. path.data: pointing to the directory where data was copied
3. 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.
