Trying to load the custom-built native-hadoop library

这个信息通常出现在使用Hadoop时,在启动时会尝试加载自定义构建的本地Hadoop库,即native-hadoop库。这个库通常是为了提高Hadoop的性能而编译的,包含了Hadoop的本地代码实现。
这个信息通常不是错误信息,而是Hadoop在启动时输出的日志信息。如果你没有自定义构建本地Hadoop库,则可以忽略这个信息。如果你确实构建了本地Hadoop库,则可以确认Hadoop是否成功地加载了该库。
如果你在使用Hadoop时遇到了其他问题,可以查看Hadoop的日志文件,了解更多详细的错误信息。Hadoop的日志文件通常位于$HADOOP_HOME/logs目录中。你可以打开相应的日志文件,查找关键字或错误信息,以便排查问题。

spark-submit 报了这个错误Trying to load the custom-built native-hadoop library
这个错误信息通常表示在运行Spark应用程序时,Spark尝试加载自定义构建的本地Hadoop库。这个库通常是为了提高Hadoop的性能而编译的,包含了Hadoop的本地代码实现。
这个错误通常是由于本地Hadoop库无法正确加载所导致的。可能的原因包括:
1. 自定义构建的本地Hadoop库不存在或已损坏。
2. Hadoop版本与自定义构建的本地Hadoop库不兼容。
解决此问题的方法是确保自定义构建的本地Hadoop库存在且可用,并且与Hadoop版本兼容。你可以尝试重新构建自定义本地Hadoop库,或者升级或降级Hadoop版本以与自定义Hadoop库兼容。
如果你不需要使用自定义构建的本地Hadoop库,可以通过将环境变量HADOOP_HOME设置为Hadoop安装目录的路径来禁用它。例如,在Linux系统上,你可以执行以下命令:
```
export HADOOP_HOME=/path/to/hadoop
```
然后再运行spark-submit命令,即可禁用自定义本地Hadoop库。
failed to load the jni shared library
This error message typically occurs when a Java program is unable to load the Java Native Interface (JNI) shared library. The JNI is a programming framework that allows Java programs to interact with native applications and libraries written in languages such as C and C++. Here are some possible reasons for this error:
1. Missing or incorrect library path: The JVM may not be able to find the JNI library because the library path is not set correctly or the library file is missing.
2. Wrong architecture: The JVM may be trying to load a JNI library that is not compatible with the architecture of the system. For example, if the JVM is 64-bit and the JNI library is 32-bit, it will not be able to load the library.
3. Incompatible Java version: The JNI library may not be compatible with the version of Java that is installed on the system.
4. Corrupted library file: The JNI library file may be corrupted, which can prevent it from loading correctly.
To resolve this error, you can try the following:
1. Check the library path: Ensure that the library path is set correctly and that the JNI library file exists in the path.
2. Check the architecture: Ensure that the JNI library file is compatible with the architecture of the system.
3. Check the Java version: Ensure that the version of Java installed on the system is compatible with the JNI library.
4. Reinstall the library: Try reinstalling the JNI library to ensure that it is not corrupted.
If none of these solutions work, you may need to consult the documentation for the specific Java program you are using or contact the developer for further assistance.
