Question

当我在Hadoop中运行一个jar文件时，我遇到了一个问题。

在终端中，我得到以下异常：

Exception in thread "main" java.io.FileNotFoundException: /var/folders/5_/hxmqt1090j1g1tqm485hr7tw0000gn/T/hadoop-unjar898783490589040837/META-INF/LICENSE (Is a directory)

我该如何解决这个问题？

我遇到了这个问题，我的代码是用scala编写的，我想用hadoop运行jar命令：像：

./bin/hadoop jar testing/learning-yarn-1.0.0.jar com.learning.yarn.simpleapp.SimpleApp

报告错误：线程＆＃34; main＆＃34;中的例外情况java.io.FileNotFoundException：/ var / folders / dy / kgryx_f11g1fdqpcnc8jl m840000gp / T / hadoop-unjar5812913115154946721 / META-INF / LICENSE（是目录）

我在Hadoop java.io.IOException: Mkdirs failed to create /some/path上修改我的maven配置库现在它已经过了。

我的maven shade插件配置如下：

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>

                        </transformers>
                        <filters>

                                </excludes>
                            </filter>
                            <filter>
                                <artifact>com.typesafe.akka</artifact>
                                <includes>
                                    <include>reference.conf</include>
                                </includes>
                            </filter>
                        </filters>
                    </configuration>
                </execution>
            </executions>
        </plugin>

如果我添加true，它将报告未找到scala类，注释掉此配置工作。祝你好运。
