Did you update the java version to 8? Did you upgrade the MySQL driver to the latest version?

Hi Folks
I migrated from Solr 4 to 7.5 and I see an issue with the way DIH is working. I use JdbcDataSource and here the config file is attached
1) I started seeing OutOfMemory issue since MySQL JDBC driver has that issue of not respecting batchSize (though Solr4 didn't show this behavior). So, I added batchSize=-1 for that
2) After adding that I'm running into ResultSet closed exception as shown below while fetching the child entity

Hello, Shashank.
The error seems similar, but I didin't find an old issue with such error.
I've found only one abandoned thread in the mailing list. ='17' seems
suspicious to me, usually it should be done via prepared statement. Have no
thoughts, maybe you can share you data config?

Hello, Shashank.
The error seems similar, but I didin't find an old issue with such error.
I've found only one abandoned thread in the mailing list. ='17' seems
suspicious to me, usually it should be done via prepared statement. Have no
thoughts, maybe you can share you data config?

Did you update the java version to 8? Did you upgrade the MySQL

driver
to the latest version?

That didn't make any difference. However, I upgraded to 8.0.15 version of mysql-jdbc driver which fixed the problem of result set closing but then data import got really slow and getting stuck without any logs in solr logs. I'll debug more from DB perspective, in the meantime any pointers would be helpful

It's worth to increase log level for DIH categories in SolrAmin. It's quite
useful usually.
