Hi, I've upgraded ES from version 2.
Current ES -
version: 5.6.1
lucene version: 6.61
While i'm trying to do a BULK insert using Bulk API, it is throwing an error "\_id" is required when version or value is set.
Is there a way to use Bulk API without providing \_id for every doc and let ES to generate a random \_id ?

Not if you are using a version, because it is expecting there may be a need to update an existing document, and it needs to be able to find it with the `_id`.
