Question

升级到ES 1.3.2后，我面临以下问题：

1）启动时出错：

[2014-08-26 11:10:20,285][ERROR][bootstrap ] {1.3.2}: Initialization Failed ...
1) NoSuchMethodError[org.elasticsearch.discovery.zen.ZenDiscovery.(Lorg/elasticsearch/common/settings/Settings;Lorg/elasticsearch/cluster/ClusterName;Lorg/elasticsearch/threadpool/ThreadPool;Lorg/elasticsearch/transport/TransportService;Lorg/elasticsearch/cluster/ClusterService;Lorg/elasticsearch/node/settings/NodeSettingsService;Lorg/elasticsearch/cluster/node/DiscoveryNodeService;Lorg/elasticsearch/discovery/zen/ping/ZenPingService;Lorg/elasticsearch/Version;)V]2) IllegalStateException[This is a proxy used to support circular references involving constructors. The object we're proxying is not constructed yet. Please wait until after injection has completed to use this object.]

2）当我尝试将cloud-aws插件升级到2.3.0版本（与ES 1.3兼容）时，我得到：

`Exception in thread "main" java.lang.UnsupportedClassVersionError: org/elasticsearch/plugins/PluginManager : Unsupported major.minor version 51.0

Java版本是： java版＆＃34; 1.7.0_45＆＃34; OpenJDK运行时环境（amzn-2.4.3.2.32.amzn1-x86_64 u45-b15） OpenJDK 64位服务器VM（构建24.45-b08，混合模式）

ES版本1.3.1和1.3.0面临同样的问题令人惊讶的是，ES v1.3.2在java版本＆＃34; 1.7.0_25＆＃34;

上运行良好

Answer 1

问题已解决。当使用不同的java版本进行编译时会出现问题，并且在运行时会发现不同版本的java。当我们查看Java -version时，它指向1.7，其中java_home指向1.6。我们还检查了命令＆＃34; java其中＆＃34;这指向1.7。当我们检查弹性搜索的脚本时，它优先于＆＃34; JAVA_HOME＆＃34;然后寻找＆＃34; java其中＆＃34;。安装了JDK 1.7（之前只有JRE 1.7），使用命令

卸载1.6

yum install java-1.7.0-openjdk
yum remove install openjdk-6-jre
yum删除java-1.6.0-openjdk

问题解决了.. !! ：）
