Subject [jira] [Commented] (SOLR-12330) Referencing non existing parameter in JSON Facet "filter" either reported too little and even might be ignored
Date Tue, 29 May 2018 07:53:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-12330?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16493197#comment-16493197
] 

Mikhail Khludnev commented on SOLR-12330:
-----------------------------------------

another NPE on omitting some values in range facets. Here's what seen on {{distrib=false}}
{quote}
 "error": {
        "trace": "java.lang.NullPointerException\n\tat org.apache.solr.search.facet.FacetRangeProcessor.createRangeList(FacetRange.java:216)\n\tat
org.apache.solr.search.facet.FacetRangeProcessor.getRangeCounts(FacetRange.java:206)\n\tat
org.apache.solr.search.facet.FacetRangeProcessor.process(FacetRange.java:98)\n\tat org.apache.solr.search.facet.FacetProcessor.processSubs(FacetProcessor.java:455)\n\tat
org.apache.solr.search.facet.FacetProcessor.fillBucket(FacetProcessor.java:407)\n\tat org.apache.solr.search.facet.FacetQueryProcessor.process(FacetQuery.java:64)\n\tat
org.apache.solr.search.facet.FacetModule.process(FacetModule.java:148)\n\tat org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:304)\n\tat
org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:173)

However, on distributed processing we have: 
{quote}
"org.apache.solr.client.solrj.SolrServerException: No live SolrServers available to handle
this request:[http://...
 "trace": "org.apache.solr.common.SolrException: org.apache.solr.client.solrj.SolrServerException:
No live SolrServers available to handle this request:[http://...
org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:416)\n\tat
org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:173)\n\tat
org.apache.solr.core.SolrCore.execute(SolrCore.java:2477)\n\tat org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:723)\n\tat
{quote}
I suppose we can't hunt for those NPE rows one by one, but rater wrap {{FacetModule}} invocation
with {{catch(Exception e) \{throw new SolrException(...,e);}}}

> Just encounter such weird behaviour, will recheck and followup. 
> {{"filter":["\{!v=$bogus}"]}} responds back with just NPE which makes impossible to guess
the reason.
> It might be even worse, since {{"filter":[\{"param":"bogus"}]}} seems like just silently
ignored.
> Once agin, I'll double check.
