----------------------------
Summary: SolrStream should not set hashq filter if numWorkers=0 or
if streamContext is not set
Key: SOLR-10490
URL: https://issues.apache.org/jira/browse/SOLR-10490
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 6.5
Reporter: kiran
Priority: Minor
SolrStream sets hashQ filter to the query even when numWorkers is zero.
partitionFilter should only be set if numWorkers > 0. Otherwise, it will lead
to error messages like
{code}

{code}
This only happens when partitionKeys is set in params and streamContext is not
set.
How to replicate: The following code will fail with the above error message^
{code}
SolrQuery query = new SolrQuery("*:*");
query.set("fq", "{!hash workers=2 worker=0}");
query.set("partitionKeys", "_version_");
query.set("distrib", "false");
String shardUrl = "http://localhost:8983/solr/test_shard1_replica1";;
SolrStream stream = new SolrStream(shardUrl, query);
stream.open();
Tuple tuple = stream.read();
{code}
