After hearing from a few people who were able to get DIH to keep working by building the jars into Solr 9, I did go back and eventually build a custom Solr image with the jars I needed in place and I did get that to work with a Solr 8 base image. I haven't tried with Solr 9 yet. In hindsight, building the jars into the image is what I should have tried first. Long term I think we probably need another solution, but I am relieved to have something running.
I'll take a look at the coordinator node. Thanks for the tip. -Sarah On 5/30/25, 5:30 PM, "Mikhail Khludnev" <m...@apache.org <mailto:m...@apache.org>> wrote: External Email - Use Caution Hello Sarah. It's hard to propose to stay on DIH, but fwiw, couldn't it still be deployed by placing jars into some /lib dir and cofiguring like in the good old days? I guess it still works and suits fine for custom images, where there's no need in runtime plugin deploy. Also, recently I added an ability to work in coordinator node in SolrCloud https://urldefense.com/v3/__https://github.com/SearchScale/dataimporthandler/pull/62__;!!CrWY41Z8OgsX0i-WU-0LuAcUu2o!y0XysA1BkGl7y928FGeslfKYcmj4SMarwfTGmHBoFVQKywOKCay0rtKQjxAhFucjpFWamUMmdwy6Hg$ <https://urldefense.com/v3/__https://github.com/SearchScale/dataimporthandler/pull/62__;!!CrWY41Z8OgsX0i-WU-0LuAcUu2o!y0XysA1BkGl7y928FGeslfKYcmj4SMarwfTGmHBoFVQKywOKCay0rtKQjxAhFucjpFWamUMmdwy6Hg$> Regarding alternatives, I looked into Apache Hop, but found it difficult to build a proper payload without a proper SolrOutputPlugin, haven't got a chance to implement it either.
