Java upgrade for solr in master-slave configuration

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

I am not aware of any changes in index format resulting from changing
your Java version.  It should not matter which machines you upgrade first.
