Hi,
I am running a self hosted ES cluster with version 6.8.1. I am trying to update some docs using update-by-query API.
It fails for some documents with following error:
version_conflict_engine_exception
version conflict, required seqNo [16893467], primary term [1]. but no document was found
I tried to find the document with GET /index/_doc/<id>
call and it returns not found, though doing a _search
by query is returning the document.
I also did a re-index and version_conflict_engine_exception is not showing up after reindexing, and also GET /index/_doc/<id>
is now returning the doc.
What is the issue with my old index? Any pointers on what the underlying issue might be?
