spark-kafka流代码对livy不起作用

我一直在用scala代码来运行spark流来采集Kafka的数据。一旦更新了所有依赖项并将新的依赖项添加到已编译的jar中，我就可以使用spark submit和代码运行它 spark-submit /codigos/codigos/adquisicion.jar . 但通过livy2运行时，在中创建流时出现异常：

val stream                          = KafkaUtils.createDirectStream[String, String](
        ssc,
        PreferConsistent,
        Subscribe[String, String](topics, kafkaParams)
    )

通过livy2运行它的代码是：

uri<-"http://192.168.0.28:8999/batches"

jsonBody2 = paste0('{ "file": "/user/bigdata/adquisicion.jar",

                     "numExecutors":1,

                     "executorCores":3,

                     "name": "Adquisición Datos",

                     "args": [""],

                     "className": "codigos.adquisicionDatos" }')

request <- httr::POST(url = uri, body = jsonBody2, httr::add_headers(.headers = c('Content-Type' = 'application/json', 'X-Requested-by'='user')))

收到的异常如下：

我在服务器上编译它，然后将它复制到docker（通过共享卷） cp ~/adquisicionDatos/target/adquisicionDatos1.2-jar-with-dependencies.jar /mnt/codigos/adquisicion.jar )并使用incrond脚本将其上载到hdfs，以便在更新时自动上载文件（工作测试）。
如果在Spark下运行 root 用户一切正常，但使用livy或running under livy 用户不工作并抛出上面的错误。

spark-kafka流代码对livy不起作用
