我有问题开始elasticsearch，启动命令是：Elasticsearch错误启动服务
cd /etc/init.d && ./elasticsearch start
出放。
/opt/jdk1.8.0_77 uno
JAVA /opt/jdk1.8.0_77/bin/java
Starting elasticsearch: [ OK ]
，但执行的状况，我得到： “elasticsearch死了，但SUBSYS锁定”
我试着删除 “elasticsearch”，在/ var /锁/ SUBSYS但是，再次生成此文件。
在日志中说。
java.lang.RuntimeException: Java version: 1.7.0_40 suffers from critical bug https://bugs.openjdk.java.net/browse/JDK-8024830 which can cause data corruption.
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.
但过程开始Java 8，
elasticsearch 26918 0.8 1.0 30526952 724324 ? Sl Jul03 1:29 /opt/jdk1.8.0_77/bin/java -Xms256m -Xmx1g -Djava.awt.headless=true -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:+DisableExplicitGC -Dfile.encoding=UTF-8 -Delasticsearch -Des.foreground=yes -Des.path.home=/opt/elasticsearch -cp :/opt/elasticsearch/lib/elasticsearch-1.7.0.jar:/opt/elasticsearch/lib/*:/opt/elasticsearch/lib/sigar/* org.elasticsearch.bootstrap.Elasticsearch
任何帮助，将不胜感激。
它使用''ps -ef | grep elasticsearch''命令输出了什么？ – Al2O3
