zookeeper 客户端报错 SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

这个错误通常是由于在运行zookeeper客户端时缺少SLF4J日志框架的实现引起的。要解决这个问题,你可以按照以下步骤进行操作:
1. 确保你的项目中包含了SLF4J的实现依赖。你可以在pom.xml文件中添加以下依赖项,以确保使用的是正确的版本:
```
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.21</version>
</dependency>
```
2. 确保你的项目中没有其他与SLF4J版本不匹配的日志框架(如log4j)的依赖项。如果有,你需要将它们与SLF4J的版本进行匹配,以避免冲突。
3. 如果你已经添加了SLF4J的实现依赖,但仍然遇到问题,请检查你的类路径,确保其中只包含了一个SLF4J的绑定实现。如果你的类路径中存在多个SLF4J绑定,可能会导致冲突和加载失败。
通过以上步骤,你应该能够解决zookeeper客户端报错"SLF4J: Failed to load class 'org.slf4j.impl.StaticLoggerBinder'"的问题。

这个输出信息是启动 HBase 的过程中出现的,其中有多个 SLF4J 绑定的警告信息,这是由于 HBase 和 Hadoop 都依赖了 SLF4J,并且使用了不同版本的 jar 包导致的。这个警告信息可以忽略,不会影响 HBase 的正常使用。如果你想要解决这个警告信息,可以尝试将 Hadoop 和 HBase 使用的 SLF4J 版本统一。另外,最后一行的输出信息表明 HBase 启动成功,可以正常使用。

这段日志提示了多个 SLF4J 绑定的问题,可能会导致日志输出异常。建议按照以下步骤进行处理:
1. 找到项目中引入的 SLF4J 相关的依赖,检查是否存在多个版本的 SLF4J 绑定。
2. 如果存在多个版本的绑定,考虑将其中一个版本的依赖排除掉,或者使用 Maven 或 Gradle 等构建工具的 Dependency Management 功能,将所有依赖的 SLF4J 版本统一。
3. 如果无法解决问题,可以参考 SLF4J 的官方文档,进行进一步的调试和处理。
