Eirik Lygre created SOLR-12659:
----------------------------------
Summary: HttpSolrClient.createMethod does not handle both stream
and large data
Key: SOLR-12659
URL: https://issues.apache.org/jira/browse/SOLR-12659
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrJ
Affects Versions: 7.4, 6.6.2
Reporter: Eirik Lygre
When using a ContentStreamUpdateRequest with stream data (through
addContentStream()), all other parameters are passed on the URL, leading to the
server failing with "URI is too large".
The code below provokes the error using Solrj 7.4, but was first seen on Solr
6.6.2. The problem is in HttpSolrClient.createMethod(), where the presence of
stream data leads to all other fields being put on the URL
h2. Example code
{code:java}
String stringValue = StringUtils.repeat('X', 16*1024);
SolrClient solr = new HttpSolrClient.Builder(BASE_URL).build();
ContentStreamUpdateRequest updateRequest = new
ContentStreamUpdateRequest("/update/extract");
updateRequest.setParam("literal.id", "UriTooLargeTest-simpleTest");
updateRequest.setParam("literal.field", stringValue);
updateRequest.addContentStream(new ContentStreamBase.StringStream(stringValue));
updateRequest.process(solr);
{code}
h2. The client sees the following error:
{code:java}
org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error
from server at http://server/solr/core: Expected mime type
application/octet-stream but got text/html. <h1>Bad Message
414</h1><pre>reason: URI Too Long</pre>
{code}
h2. Error fragment from HttpSolrClient.createMethod
{code}
if(contentWriter != null) {
String fullQueryUrl = url + wparams.toQueryString();
HttpEntityEnclosingRequestBase postOrPut = SolrRequest.METHOD.POST ==
request.getMethod() ?
new HttpPost(fullQueryUrl) : new HttpPut(fullQueryUrl);
{code}
