I have some index data stored in hdfs (ES compatible indexing) and rest in ES and also ES and hdfs clusters are different. Is there any other better alternative than below options 1. Bulk index request - but it is unnecessary as the data is already in indexed format 2. Move/copy periodically hdfs to ES and merge indices in ES Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
