Java 编译apache sparkSql时出错

我试图执行下面的sparkSQL示例

my pom.xml（我还添加了sql依赖项，我被卡住了，请帮助）

我发现了这个问题：

在这个例子中

替换行

schemaPeople.registerEmptable（“人”）

使用
schemaPeople.registerAsTable（“人”）

使用
mvn编译和打包编译
和
mvn打包
并使用运行

bin/spark-submit --class "org.apache.spark.examples.sql.SimpleApp" --master local[4] try/simple-project/target/simple-project-1.0.jar

似乎程序在schemaPeople.registerEmptable（“人”）上抛出错误；我一直在查Spark JavaDoc。。找不到任何线索。。我是不是遗漏了什么
