mvn 编译Spark代码的时候常见错误:
[ERROR] Failed to execute goal on project spark-tools_2.11: Could not resolve dependencies for project org.apache.spark:spark-tools_2.11:jar:2.4.3: Failed to collect dependencies at org.clapper:classutil_2.11:jar:1.1.2: Failed to read artifact descriptor for org.clapper:classutil_2.11:jar:1.1.2: Could not transfer artifact org.clapper:classutil_2.11:pom:1.1.2 from/to alimaven (http://maven.aliyun.com/nexus/content/groups/public/): java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty -> [Help 1]
[ERROR]
截图如下：
单独切换到tools模块
获取详细的报错信息
cd tools mvn -Pkubernetes -Phadoop-2.7 -Dhadoop.version=2.7.3 -Phive -Phive-thriftserver -DskipTests clean package -e

这里需要分析底层的调用，其实就是java请求http的时候出现安全检查问题
我们忽略安全检查
mvn -Pkubernetes -Phadoop-2.7 -Dhadoop.version=2.7.3 -Phive -Phive-thriftserver -DskipTests clean package -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true
即可成功
