Component/s: contrib - DataImportHandler

> ----------------------------------------------------------------------------------------
>
> Key: SOLR-6771
> URL: https://issues.apache.org/jira/browse/SOLR-6771
> Project: Solr
> Issue Type: Bug
> Components: contrib - DataImportHandler
> 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:
