JVM/DVM/ART

这是一个IT类问题。JVM(Java Virtual Machine)是Java虚拟机的缩写,它是Java程序运行的环境。DVM(Dalvik Virtual Machine)是Android系统早期使用的虚拟机,用于执行Dalvik字节码。而ART(Android Runtime)是Android系统目前使用的运行时环境,取代了DVM,提供更高的性能和效率。

NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
This error occurs when the JVM is unable to find a particular class at runtime. In this case, the class it's looking for is `kotlin/jvm/internal/Intrinsics`, which is a class used by the Kotlin compiler to generate optimized bytecode.
There are a few possible reasons why this error might occur:
1. The Kotlin runtime library is not included in the classpath. Make sure you have included the Kotlin runtime library in your project's dependencies.
2. The version of Kotlin you are using is not compatible with the version of the JVM you are running. Make sure you are using a version of Kotlin that is compatible with your JVM.
3. There might be a problem with your build configuration. Make sure your build configuration is set up correctly and that all necessary dependencies are included.
To solve this error, you can try the following:
1. Make sure you have included the Kotlin runtime library in your project's dependencies.
2. Make sure you are using a version of Kotlin that is compatible with your JVM.
3. Check your build configuration and make sure it is set up correctly.
4. If none of these solutions work, try cleaning and rebuilding your project.
hadoop@master:~$ echo $CLASSPATH .:/usr/lib/jvm/jdk1.8.0_162/lib:/usr/lib/jvm/jdk1.8.0_162/jre/lib
根据提供的引用内容,您可以通过以下步骤来回答问题:
1. 打开hadoop用户的环境变量配置文件:
```shell
vim ~/.bashrc
```
2. 在文件的开头位置添加以下行内容:
```shell
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_162
export JRE_HOME=${JAVA_HOME}/j
export CLASSPATH=.:${JAVA_HOMElib:${JRE_HOME}/lib
export PATHJAVA_HOME}/bin:$PATH
```
3. 保存并退出文件。
4. 重新加载环境变量文件:
```shell
source ~/.bashrc
```
5. 检查CLASSPATH环境变量是否已经更新:
```shell
echo $CLASSPATH
```
您应该会看到类似以下输出:
```
.:/usr/lib/jvm/jdk1.8.0_162/lib:/usr/lib/jvm/jdk1.8.0_162/jre/lib
```
