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)? We've used JDK 8u20 without issues on our dev servers but it would be nice to have some guidance on this since we are moving to production soon with this. The reason we're using Java 8 is because we are using that for our apps as well and it is kind of nice to have just one jdk to worry about. Also, I suspect there may be some perfomance benefits given the amount of change that went into e.g. hotspot. In general, an overview of common vms and status with respect to elasticsearch would be nice to have somewhere. There are quite a few different suppliers of vms at this point and picking one seems to be a bit of a black art & leap of faith currently. There's Openjdk, oracle jdk, Azul's Zulu (essentially openjdk as far as I know), and Azul's Zulu Enterprise. You can get each of these for Java 6, 7, and 8. Especially for openjdk, it also matters how it was built. Jilles -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
