I have a requirment where for some data setting the '\_source' in indexrequest is strightforward but for some huge amount of data I need to run long running activity to generate data which needs to be indexed. So frequently I plan to take a snapshot from ES to Hadoop and want to add new lucene documents (using lucene 4.7x library not elasticsearch library) in hadoop by running a batch job and finally restore this modified index repo/snapshot to ES. Is it possible to update snapshot data and restore? If so, how to get handle of Lucene (org.apache.lucene.store.Directory) which stored in hdfs and addDocument using indexwriter Is there any other better alternative to achieve the above requirement?

No I don't believe so. The snapshot data is not really a "valid" Lucene index, per se. It does contain segment files, but they are named and packaged in a specific manner that it would be best not to mess with them. 😉 -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Could please suggest a best option for merging index data stored in HDFS with the index data stored in ES node On Saturday, May 31, 2014 1:45:13 AM UTC+5:30, Binh Ly wrote: > No I don't believe so.
