I am using CDH 15.5, which comes with Solr 4.10
I ran into issues indexing a csv document, in the schema config i had specified a uniqueKey value, for some reason it kept giving me a "org.apache.solr.common.SolrException: Document contains multiple values for uniqueKey field: id" -- I've asked about this in a separate thread.
So i removed the uniqueKey constraint in the configurations, then i ran into another error -- "QueryElevationComponent requires the schema to have a uniqueKeyField" , this means uniqueKey definition is enforced in the solrconfig.xml file. I subsequently disabled this from the Solrconfig.xml, and was able to successfully index the file.
However when i try to query from the Solr admin using the Select handler, i get an exception below.
A quick glance through the stacktrace shows that the null exception is returned in the createMainQuery method.
https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/handler/compone...
String keyFieldName = rb.req.getSchema().getUniqueKeyField().getName();
In the method definition of CreateMainQuery, there's an attemp to assign a certain variable the uniqueKeyField, which if not enabled means its null, hence the null exception.

Can anyone confirm they've ran into this issue with CDH 15.5
