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.

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 [choweiyuan@gmail.com](mailto:choweiyuan@gmail.com) 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. > > [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/setup.html) > > [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/blog/java-1-7u55-safe-use-elasticsearch-lucene/) > > [Elasticsearch Platform — Find real-time answers at scale | Elastic](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.
