Ok, understood. Don't use option (1) / NFS-HDFS.
So but thats all my options ? There isn't an option (3) where all my data is persisted in HDFS but the nodes operate on a local copy or anything like that !?
What I think @ssatapathy is suggesting is to keep your data in HDFS (primary storage) and load it through Hadoop jobs into ES. ES is using the out of the box configuration, writing data to the local disks/storage.
