Sachin Kale commented on SOLR-6545:
-----------------------------------
We are running 4.10.0 on Production and we are getting tons of
NullPointerException due to this bug. Though we are using SolrCloud setup, we
are having only one shard, so it is a basically master-slave configuration
only. In one of the comments, it is mentioned that, this bug occurs when doing
distributed queries only. How do I disable the distributed queries?

> Key: SOLR-6545
> URL: https://issues.apache.org/jira/browse/SOLR-6545
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.10
> Environment: Mac OS X 10.9.5, Ubuntu 14.04.1 LTS
> Reporter: Burke Webster
> Assignee: Shalin Shekhar Mangar
> Priority: Critical
> Attachments: SOLR-6545.patch
>
>
> Downloaded 4.10.0, unpacked, and setup a solrcloud 2-node cluster by running:
> bin/solr -e cloud
> Accepting all the default options and you will have a 2 node cloud running
> with replication factor of 2.
> Now add 2 documents by going to example/exampledocs, creating the following
> file named my_test.xml:
> <add>
> <doc>
> <field name="id">1000</field>
> <field name="name">test 1</field>
> <field name="desc_t">Text about test 1.</field>
> <field name="cat_A_s">Category A</field>
> </doc>
> <doc>
> <field name="id">1001</field>
> <field name="name">test 2</field>
> <field name="desc_t">Stuff about test 2.</field>
> <field name="cat_B_s">Category B</field>
> </doc>
> </add>
> Then import these documents by running:
> java -Durl=http://localhost:7574/solr/gettingstarted/update -jar post.jar
> my_test.xml
> Verify the docs are there by hitting:
> http://localhost:8983/solr/gettingstarted/select?q=*:*
> Now run a query and ask for only the id and cat_*_s fields:
> http://localhost:8983/solr/gettingstarted/select?q=*:*&fl=id,cat_*
> You will only get the id fields back. Change the query a little to include a
> third field:
> http://localhost:8983/solr/gettingstarted/select?q=*:*&fl=id,name,cat_*
> You will now get the following exception:
> java.lang.NullPointerException

> I believe SOLR-6501 partially fixes the issue. After downloading build 607
> (4.11.0-2014-09-11_22-31-51 1624413 - jenkins - 2014-09-11 22:32:47) which
> contains the fix for SOLR-6501 and going through the same setup as above, I
> still see some issues but no exceptions are thrown.
> With build 607, running a query for id and a wild card field still does't
> work:
> http://localhost:8983/solr/gettingstarted/select?q=*:*&fl=id,cat_*
> It returns only the id field. If I add another field into the list it
> finally works:
> http://localhost:8983/solr/gettingstarted/select?q=*:*&fl=id,name,cat_*
> Returns id, name, and the cat_*_s fields.
