[jira] [Created] (SOLR-6771) Sending DIH request to non-leader can
result in different number of successful documents
Greg Harris created SOLR-6771:
---------------------------------
Summary: Sending DIH request to non-leader can result in different number of successful documents
Key: SOLR-6771
URL: https://issues.apache.org/jira/browse/SOLR-6771
Project: Solr
Issue Type: Bug
Affects Versions: 4.10
Reporter: Greg Harris
Basically if you send a DIH request to the non-leader the following set of circumstances can occur:
1) If there are errors in some of the documents the request itself is rejected by the leader (try making a required field null with some documents to make sure there are rejections).
2) This causes all documents on that request to appear to fail. The number of documents that a follower is able to update DIH with appears variable.
3) You need to use a large number of documents it appears to see the anomaly.
This results in the following error on the follower:
