Subject [jira] [Created] (SOLR-13204) ArrayIndexOutOfBoundsException in org/apache/solr/search/grouping/endresulttransformer/MainEndResultTransformer.java[36]
Date Thu, 31 Jan 2019 13:35:00 GMT
Marek created SOLR-13204:
----------------------------

             Summary: ArrayIndexOutOfBoundsException in org/apache/solr/search/grouping/endresulttransformer/MainEndResultTransformer.java[36]
                 Key: SOLR-13204
                 URL: https://issues.apache.org/jira/browse/SOLR-13204
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: master (9.0)
         Environment: h1. Steps to reproduce

* Use a Linux machine.
*  Build commit {{ea2c8ba}} of Solr as described in the section below.
* Build the films collection as described below.
* Start the server using the command {{./bin/solr start -f -p 8983 -s /tmp/home}}
* Request the URL given in the bug description.

h1. Compiling the server

{noformat}
git clone https://github.com/apache/lucene-solr
cd lucene-solr
git checkout ea2c8ba
ant compile
cd solr
ant server
{noformat}

h1. Building the collection and reproducing the bug

We followed [Exercise 2|http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html#exercise-2]
from the [Solr Tutorial|http://lucene.apache.org/solr/guide/7_5/solr-tutorial.html].

{noformat}
mkdir -p /tmp/home
echo '<?xml version="1.0" encoding="UTF-8" ?><solr></solr>' > /tmp/home/solr.xml
{noformat}

In one terminal start a Solr instance in foreground:
{noformat}
./bin/solr start -f -p 8983 -s /tmp/home
{noformat}

In another terminal, create a collection of movies, with no shards and no replication, and
initialize it:

{noformat}
bin/solr create -c films
curl -X POST -H 'Content-type:application/json' --data-binary '{"add-field": {"name":"name",
"type":"text_general", "multiValued":false, "stored":true}}' http://localhost:8983/solr/films/schema
curl -X POST -H 'Content-type:application/json' --data-binary '{"add-copy-field" : {"source":"*","dest":"_text_"}}'
http://localhost:8983/solr/films/schema
./bin/post -c films example/films/films.json
curl -v "URL_BUG"
{noformat}

Please check the issue description below to find the "URL_BUG" that will allow you to reproduce
the issue reported.

            Reporter: Marek


Requesting the following URL causes Solr to return an HTTP 500 error response:

{noformat}
solr/films/select?group=true&distrib=true&group.main=true
{noformat}

The error response seems to be caused by the following uncaught exception:

{noformat}
ERROR (qtp689401025-18) [   x:films] o.a.s.s.HttpSolrCall null:java.lang.ArrayIndexOutOfBoundsException:

There is accessed the first element of an empty array of strings, stored in the member 'org.apache.solr.search.grouping.GroupingSpecification.fields'.
There is an attept to put some strings to the array at org/apache/solr/handler/component/QueryComponent.java[283];
however, the string "group.field" is not present in params of the processed org.apache.solr.request.SolrQueryRequest
instance.

Look into section 'Environment' above to see installation step of Solr and films collection.
