Elasticsearch 1.3.2升级后的问题

Question

升级到ES 1.3.2后,我遇到以下问题:

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(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"1.7.0_45"OpenJDK运行时环境(amzn-2.4.3.2.32.amzn1-x86_64 u45-b15)OpenJDK 64位服务器VM(内置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"1.7.0_25"上工作正常

Answer 1

问题得到解决.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.我们还检查了指向1.7的命令"java which".当我们检查弹性搜索的脚本时,它优先于"JAVA_HOME",然后查找"java which".安装了JDK 1.7(之前只有JRE 1.7),使用命令卸载了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.. !! :)
