can you be more specific about " It just waits and eventually fails after about 2 minutes." ... what message does it print to the consolr? what does the solr log file say?

I was trying to : upgrade from 8.5 to 9.3. That introduced a few errors into our website : search that we were not able to resolve, so we've figured we'll just : upgrade to the latest 8.x version, ie. 8.11. : : We've successfully upgraded the underlying OS, and we're happy 8.11 returns : the same search results as 8.5. So far so good. : : Now we're looking at java. Its currently running on openjdk-8. I've tried : upgrading to openjdk-11 and openjdk-13. The process, as this is Ubuntu is : basically. : apt install openjdk-13-jdk : update-alternatives --list java : update-alternatives --set java /usr/lib/jvm/java-13-openjdk-amd64/bin/java : On doing that, solr will fail to start. It just waits and eventually fails : after about 2 minutes. So I can do : update-alternatives --set java : /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java : To set it back to java 8 and it runs again. : : I've tried regenerating the init script with the new java, but the scripts : are identical. I've tried rebooting the server with the new java active in : case its an environment thing. But to no avail. : : Any ideas what's going on here? : : I notice java 8 is still getting updates, so maybe the path of least : resistance is to stay on that. : : Jim : -Hoss http://www.lucidworks.com/
