Hi Jilles, 1.7u55 has indeed be the recommended version for a long time, but JDK 8u25 is fine too. The page that you linked is from elasticsearch-hadoop and might be a bit outdated, we are trying to keep up to date information about recommended JVMs at the following URL: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html#jvm-version
For reference we are also trying to improve our startup scripts so that they would fail to start if you are using a JVM with known issues. See for instance https://github.com/elasticsearch/elasticsearch/pull/7580 On Thu, Oct 16, 2014 at 1:03 PM, Jilles van Gurp <jillesvang...@gmail.com> wrote: > I know JDK 7u55 was labeled as OK some time ago and this is still listed > as the official requirement: > http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/requirements.html > > However, time has moved on and I was wondering what the testing status and > advice is for more recent JDKs. > > Particularly, I'd like to know whether Oracle JDK 8u25 safe for production > use (on centos 7)?
