Spark 提交任务时 Invalid signature file digest 错误

第一次用  spark-submit 提交任务，是 Scala 的程序，命令格式是

spark-submit --class <main-class> --master local[*] --name "My first Spark Job" spark-test-fat-1.0-SNAPSHOT.jar

结果报出错误

Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
at sun.security.util.SignatureFileVerifier.processImpl(SignatureFileVerifier.java:330)
at sun.security.util.SignatureFileVerifier.process(SignatureFileVerifier.java:263)

Google 查了下，是须要把 jar 文件中的 META-INF/*.RSA META-INF/*.DSA META-INF/*.SF 文件清理掉。咱们能够执行以下命令从现有的 jar 中除去

zip -d <jar file name>.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF

是由于 jar 包中包含有这些文件才形成提交 Spark 时验证文件签名摘要时失败。 阅读全文 >>
