问题描述

当我尝试在Windows 10上运行Elasticsearch，因为主要语言是英语，一切正常.但是，如果我将主要语言更改为土耳其语，我会收到错误消息，例如:

2018-07-26 14:42:39,645 main ERROR Null object returned for Delete in DefaultRolloverStrategy.

因此，这似乎是一个charset问题.该文件被编码为UTF-8，我使用记事本++进行检查. Elasticsearch具有JVM选项-Dfile.encoding=UTF-8.我仔细检查了log4j2.properties文件，IfFileName没有空间.

，如果我更改IfFileName为ıfFileName(ı是土耳其字符 - 较低i)错误变为:

2018-07-26 14:54:25,819 main ERROR Unable to locate plugin type for Ä±fFileName

有人知道如何解决这个问题吗?

其他推荐答案

我遇到了相同的问题(它发生在我使用elasticsearch的Sonarqube安装中.)，但不知道在哪里添加-Duser.language=en.但是，我发现它是在声纳的下方.

其他推荐答案

这是log4j2中的一个错误，它使用 String#toLowerCase() 没有区域参数:在土耳其语言环境中，IfFileName在ıffilename(带有无用的I i i i i i i i) ).我已将其报道为 gh问题#1281 .

在修复此操作之前，您可以在所有小写字母(英语)字母中编写插件类型:例如iffilename而不是IfFileName.

When I try to run Elasticsearch on Windows 10 as main language is English, everything works fine. But if I change the main language as Turkish, I get error messages as:

So it seem like a charset problem. The file is encoded as UTF-8, I check it with Notepad++. Elasticsearch has JVM option -Dfile.encoding=UTF-8. I double checked the log4j2.properties file and IfFileName has no space after it.

And if I change IfFileName as ıfFileName (which ı is a Turkish character - lower I) error becomes:

2018-07-26 14:54:25,819 main ERROR Unable to locate plugin type for Ä±fFileName

Does anyone have an idea about how to fix that?

其他推荐答案

I had the same problem (it happened in the sonarqube installation for me which uses elasticsearch.) but didn't know where to add the -Duser.language=en. However, I found it out it is under the sonar.properties, the line where sonar.search.javaAdditionalOpts= is located remove the # at the begining and write as sonar.search.javaAdditionalOpts=-Duser.language=en and save the file.

其他推荐答案

This is a bug in Log4j2, which uses String#toLowerCase() without a locale parameter: in the Turkish locale IfFileName is lowercased as ıffilename (with a dotless i). I have reported this as GH issue #1281.

Until this is fixed you can write plugin types in all lowercase (English) letters: e.g. iffilename instead of IfFileName.
