> Update Operations via SOLR to Knox Fail
> ----------------------------------------
>
> Key: KNOX-1066
> URL: https://issues.apache.org/jira/browse/KNOX-1066
> Project: Apache Knox
> Issue Type: Bug
> Components: Site
> Affects Versions: 0.12.0, 0.13.0
> Reporter: Rick Kellogg
> Assignee: Rick Kellogg
> Fix For: 0.14.0
>
> Attachments: PreemptiveHttpSolrClient.java
>
>
> When using the Java SOLRJ HttpSolrClient, any operation that relies upon a
> POST HTTP operation fails authentication when proxied via Knox. This is
> because the SOLRJ API only supports traditional challenge/response basic
> authentication. For any update style operation the SOLRJ client refuses to
> retry the operation as it might lead to duplicate data, etc. If this were a
> GET operation, it would retry the operation and include the appropriate
> authentication header.
> Therefore preemptive authentication must be used for updates to succeed.
> Unfortunately, the Apache HttpClient construction is hidden from the client
> in the form of the HttpSolrClient.Builder class.
