Gus Heck created SOLR-9495:
------------------------------

             Summary: AIOBE with confusing message for incomplete sort spec in Streaming Expression
                 Key: SOLR-9495
                 URL: https://issues.apache.org/jira/browse/SOLR-9495
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: search
    Affects Versions: 6.2
         Environment: 6.2.0_RC1
            Reporter: Gus Heck
            Priority: Minor


I was thinking of using streaming expressions for something, and started to play around with
it, but I made a bonehaded mistake, and got an error that's pretty confusing: 

{code}{"result-set":{"docs":[
{"EXCEPTION":"1","EOF":true}]}}{code}

This turns out to be due to: 
{code}
	at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:572)
	at java.lang.Thread.run(Thread.java:745)

	at org.apache.solr.client.solrj.io.stream.CloudSolrStream.<init>(CloudSolrStream.java:181)
	... 38 more
{code}

The mistake I made was omitting a direction from the sort spec. Attaching trivial patch to
provide a better error message...
