-----------------------------------

             Summary: static caches in StreamHandler ought to move to 
CoreContainer lifecycle
                 Key: SOLR-14423
                 URL: https://issues.apache.org/jira/browse/SOLR-14423
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: streaming expressions
            Reporter: David Smiley


StreamHandler (at "/stream") has several statically declared caches.  I think 
this is problematic, such as in testing wherein multiple nodes could be in the 
same JVM.  One of them is more serious -- SolrClientCache which is 
closed/cleared via a SolrCore close hook.  That's bad for performance but also 
dangerous since another core might want to use one of these clients!
