flume启动SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]
时间: 2024-06-04 16:06:16 浏览: 16
这个日志信息表示,Flume使用了SLF4J作为日志门面,但是实际的日志实现是Log4jLoggerFactory而不是SLF4J自己的默认实现。这是因为Flume默认使用了Log4j作为日志实现,而不是SLF4J提供的简单日志实现。
这个信息并不是错误,而是提醒你当前使用的日志实现是Log4jLoggerFactory。如果你想使用SLF4J提供的简单日志实现,你需要手动配置Flume使用SLF4J桥接Log4jLoggerFactory。你可以在Flume的配置文件中配置log4j.logger.org.apache.flume=INFO来控制Flume的日志输出级别。

log4j:WARN No appenders could be found for logger (org.apache.flume.node.PollingPropertiesF
log4j:WARN No appenders could be found for logger (org.apache.flume.node.PollingPropertiesFileConfigurationProvider).
This warning message indicates that the log4j framework was unable to find any appenders configured for the specified logger. An appender is responsible for outputting log messages to a specific destination, such as a file, console, or database.
To resolve this issue, you need to configure an appender for the logger mentioned in the warning message. This can be done by adding an appropriate appender configuration to your log4j configuration file. The configuration file is typically named log4j.properties or log4j.xml and should be present in your application's classpath.
Here is an example of a basic appender configuration for writing logs to a file:
```
log4j.rootLogger=INFO, file
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=/path/to/log/file.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
```
In this example, the `log4j.rootLogger` sets the logging level to INFO and associates it with the `file` appender. The `file` appender is configured to write logs to the specified file path (`/path/to/log/file.log`) using the specified layout pattern.
Make sure to adjust the file path and other settings according to your requirements. Once you have added the appender configuration, restart your application, and the warning should no longer appear.

这个警告是由于在Flume配置中找不到适当的日志记录器(appender)导致的。要解决这个问题,您需要在您的Flume配置文件中添加一个日志记录器。
您可以在Flume配置文件中添加以下内容来配置一个简单的日志记录器:
```
# flume.conf
# 定义一个日志记录器
agent1.sources = source1
agent1.sinks = sink1
agent1.channels = channel1
# 设置日志级别为INFO
agent1.sources.source1.channels = channel1
agent1.sources.source1.type = ...
agent1.sources.source1.channels = channel1
agent1.sources.source1.selector.type = ...
agent1.sinks.sink1.channel = channel1
agent1.sinks.sink1.type = ...
agent1.sinks.sink1.channel = channel1
agent1.channels.channel1.type = ...
```
在这个例子中,我们通过`agent.sources`、`agent.sinks`和`agent.channels`定义了一个简单的Flume agent。您可以根据您的实际配置进行调整。
请确保将`agent.sources.source1.type`、`agent.sinks.sink1.type`和`agent.channels.channel1.type`替换为适当的类型。
希望这可以帮助您解决问题!如果还有其他问题,请随时提问。
