Hi, I am currently working with Java-1.7, Solr-4.8.1 with tomcat 7. The solr configuration has slave & master architecture. I am looking forward to upgrade Java from 1.7 to 1.8 version in order to take advantage of memory optimization done in latest version.
So, I am confused if I should upgrade java first on master server and then on slave server or the other way round. What should be the ideal steps, so that existing solr index and other things should not get corrupted . Please suggest. Regards Kamal
