Hello everyone ! I wanted to try Elasticsearch 2.0 with Kibana and Logstash, but all is not perfect (not choice of color, not ticket etc...) And I want go back in 1.7 for Graylog. But I have some errors! > 6 errors > at org.elasticsearch.common.inject.internal.Errors.throwCreationExceptionIfErrorsExist(Errors.java:344) > at org.elasticsearch.common.inject.InjectorBuilder.injectDynamically(InjectorBuilder.java:178) > at org.elasticsearch.common.inject.InjectorBuilder.build(InjectorBuilder.java:110) > at org.elasticsearch.common.inject.Guice.createInjector(Guice.java:93) > at org.elasticsearch.common.inject.Guice.createInjector(Guice.java:70) > at org.elasticsearch.common.inject.ModulesBuilder.createInjector(ModulesBuilder.java:59) > at org.elasticsearch.node.internal.InternalNode.(InternalNode.java:210) > at org.elasticsearch.node.NodeBuilder.build(NodeBuilder.java:159) > at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:77) > at org.elasticsearch.bootstrap.Bootstrap.main(Bootstrap.java:245) > at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:32) What's the problem ? It's because Elastic 2.0 is still present on my Ubuntu ? Thank you so much for your reply. ---

If you made a backup of the data before hand then you should be able to just remove 2.0, restore the backup, and move on. If you didn't, then I don't believe you are likely to be able to go back. Sadly, guice exceptions are impossible to excerpt. I might be able to figure out what is going on from the exception, but only if you post the whole thing in a gist or something. Though if you don't have the old data its kind of a moot point. ---

Problem : resolved. I'm not sure the problem was logstash and Kibana, when i have seen their was running, after I kill her process, purge elasticsearch and reinstall him, all is ok. Thank you for your help @nik9000 ---
