[kkomv (Vamshi)]

Installation is failing with the below error ,

{1.6.0}: Initialization Failed ...

• RuntimeException[Java version: 1.7.0_51 suffers from critical bug https://bugs.openjdk.java.net/browse/JDK-8024830 which can cause data corruption https://bugs.openjdk.java.net/browse/JDK-8024830%20which%20can%20cause%20data%20corruption .
  Please upgrade the JVM, see http://www.elastic.co/guide/en/elasticsearch/reference/current/_installation.html for current recommendations.
  If you absolutely cannot upgrade, please add -XX:-UseSuperWord to the JVM_OPTS environment variable.
  Upgrading is preferred, this workaround will result in degraded performance.]

our current java version is

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)

What should be the minimum required JVM version that we need to upgrade to on java 1.7, cannot move to java 1.8

Thanks Mark, how do I make elasticsearch to use the upgraded jre which is installed at a different path and not the one at JAVA_HOME. The existing 1.7.0_51 JRE at JAVA_HOME is used by several other java processes on this server and do not want to impact them.

Its different depending on how you've installed Elasticsearch. If you used the .deb you put it in /etc/defaults/elasticsearch as

JAVA_HOME=/usr/share/SOME_OTHER_JAVA
