Subject [jira] [Commented] (SOLR-13414) Sql Schema is not initializing
Date Fri, 19 Apr 2019 16:21:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-13414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16822025#comment-16822025
] 

Joel Bernstein commented on SOLR-13414:
---------------------------------------

I attached two things:

1) A new jar for solr-core built from branch_7x. It should be basically the same as 7.7.1
as dev has stopped on the 7x branch.

2) A patch file with the change.

This outputs a line to the console log file with information about which field is being loaded
from the schema and if the field info is null. I believe this will show us which field is
causing the null pointer.

You can replace the solr-core.jar with the binary here. Keep a copy of the old jar and copy
it back when done.

> When attempting to create a JDBC sql query against a large collection (400m + records)
we get a null error.
> After initial discussion in solr-user I have been asked to open this ticket - The exception
thrown does not provide sufficient detail to understand the underlying problem. Its it thought
to be an issue with the schema not initialising correctly. 
> Attached is the managed-schema after a downconfig.
