потоковый код искры кафки не работает на livy

0 голосов
/ 06 ноября 2018

Я работал над некоторыми scala кодами для запуска потоковой передачи искры для сбора данных kafka. После обновления всех зависимостей и добавления новых в скомпилированный jar я могу запустить его с помощью spark-submit с кодом spark-submit /codigos/codigos/adquisicion.jar. Но при запуске через livy2 я получаю исключение при создании потока в: 

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

Код, используемый для запуска через livy2: 

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')))

А полученное исключение следующее: 

    18/11/06 08:01:00 ERROR ApplicationMaster: User class threw exception: java.lang.NoClassDefFoundError: org/apache/kafka/clients/consumer/Consumer

Я компилирую его на сервере, а затем копирую в докер (через общий том cp ~/adquisicionDatos/target/adquisicionDatos1.2-jar-with-dependencies.jar /mnt/codigos/adquisicion.jar) и загружаю его в HDFS, используя сценарий incrond для автоматической загрузки файлов при обновлении (работает, проверено).

При работе с spark-submit под root user все работает нормально, но с использованием livy или под livy пользователь не работает и выдает ошибку выше.
