Estou usando o comando spark-submit que tenho para que as propriedades do log4j invoquem um envio do Spark assim:

/opt/spark-1.6.2-bin-hadoop2.6/bin/spark-submit \
--driver-java-options \
"-Dlog4j.configuration=file:/home/test_api/log4j-driver.properties\ --class Test testing.jar

Como eu faço--driver-java-options, para enviar um trabalho via curl (API REST oculta do Apache Spark)?

Eu tentei isso:

curl -X POST http://host-ip:6066/v1/submissions/create --header "Co,ntent-Type:application/json;charset=UTF-8" --data '{
"action" : "CreateSubmissionRequest",
"appArgs" : [ "" ],
"appResource" : "hdfs://host-ip:9000/test/testing.jar",
"clientSparkVersion" : "1.6.2",
"environmentVariables" : {
"SPARK_ENV_LOADED" : "1"
},
"mainClass" : "Test",
"spark.driver.extraJavaOptions" : "-Dlog4j.configuration=file:/home/test_api/log4j-driver.properties",
"sparkProperties" : {
"spark.jars" : "hdfs://host-ip:9000/test/testing.jar",
"spark.app.name" : "Test",
"spark.eventLog.enabled": "true",
"spark.eventLog.dir": "hdfs://host-ip:9000/test/spark-events",
"spark.submit.deployMode" : "cluster",
"spark.master" : "spark://host-ip:7077"
}
}'

Trabalho enviado com sucesso e a resposta foi fornecida, mas com um uknownField:

{
  "action" : "CreateSubmissionResponse",
  "message" : "Driver successfully submitted as driver-20160810210057-0091",
  "serverSparkVersion" : "1.6.2",
  "submissionId" : "driver-20160810210057-0091",
  "success" : true,
  "unknownFields" : [ "spark.driver.extraJavaOptions" ]
}

"unknownFields" : [ "spark.driver.extraJavaOptions" ]

Eu também tenteidriverExtraJavaOptions do seguinte modo:

curl -X POST http://host-ip:6066/v1/submissions/create --header "Content-Type:application/json;charset=UTF-8" --data '{
"action" : "CreateSubmissionRequest",
"appArgs" : [ "" ],
"appResource" : "hdfs://host-ip:9000/test/testing.jar",
"clientSparkVersion" : "1.6.2",
"environmentVariables" : {
"SPARK_ENV_LOADED" : "1"
},
"mainClass" : "Test",
"driverExtraJavaOptions" : "-Dlog4j.configuration=file:/home/test_api/log4j-driver.properties",
"sparkProperties" : {
"spark.jars" : "hdfs://host-ip:9000/test/testing.jar",
"spark.app.name" : "Test",
"spark.eventLog.enabled": "true",
"spark.eventLog.dir": "hdfs://host-ip:9000/test/spark-events",
"spark.submit.deployMode" : "cluster",
"spark.master" : "spark://host-ip:7077"
}
}'

Mas obteve uma resposta semelhante:

{
  "action" : "CreateSubmissionResponse",
  "message" : "Driver successfully submitted as driver-20160810211432-0094",
  "serverSparkVersion" : "1.6.2",
  "submissionId" : "driver-20160810211432-0094",
  "success" : true,
  "unknownFields" : [ "driverExtraJavaOptions" ]
}

Por que é isso?
