The recommendations for ElasticSearch Java versions are pretty rigid. There are bugs in various JREs that affect Lucene and ElasticSearch. 1.7.0_60 seems to work correctly, at least for ES 1.3.4. (1.7.0_67 does not - it doesn't deal with empty data fields the way the ES docs say it should.) I recommend 1.7.0_60 as a good stable version, and at least at one point, that specific version was publicly mentioned for ES installs... I don't know anything about 1.8...
The first link you provide says it all: using a non-recommended JVM prior to 1.7.0_55 can lead to data corruption and loss. Don't do it. -- Les On Sat, Dec 13, 2014 at 5:28 PM, Wei Yuan Cho <[email protected]> wrote: > > Hi > > I am using Elasticsearch 1.4.1 and have read from the following links that* > Java 1.7.0.55* and above are the recommended version to run Elasticsearch > with. > > http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html > > http://www.elasticsearch.org/blog/java-1-7u55-safe-use-elasticsearch-lucene/ > > http://www.elasticsearch.org/blog/elasticsearch-1-2-0-released/ > > From the last blog post it has been pointed out that the bug that causes > index corruption is between 1.7.0.25 to 1.7.0.55.
