Question

spark-submit --packages com.databricks:spark-redshift_2.11:2.0.1 --jars /usr/share/aws/redshift/jdbc/RedshiftJDBC4.jar /home/hadoop/test.py

如何以Apache livy格式指定上述（pyspark）spark-submit命令？

我尝试了以下操作：

    curl -X POST --data '{"file": "/home/hadoop/test.py", "conf": 
    {"com.databricks": "spark-redshift_2.11:2.0.1"}, \
    "queue": "my_queue", "name": "Livy  Example",  "jars" : 
    "/usr/share/aws/redshift/jdbc/RedshiftJDBC4.jar"}', \
    -H "Content-Type: application/json" localhost:8998/batches

Refered the following livy article spark livy rest api

也出现以下错误：

"Unexpected character ('“' (code 8220 / 0x201c)): was expecting double-quote to start field name\n at [Source: (org.eclipse.jetty.server.HttpInputOverHTTP); line: 1, column: 37]

您的命令错误，请使用以下示例构造命令。

火花提交命令

./bin/spark-submit \
--class org.apache.spark.examples.SparkPi \

--jars a.jar,b.jar \

--pyFiles a.py,b.py \

--files foo.txt,bar.txt \

--archives foo.zip,bar.tar \

--master yarn \

--deploy-mode cluster \

--driver-memory 10G \

--driver-cores 1 \

--executor-memory 20G \

--executor-cores 3 \

--num-executors 50 \

--queue default \

--name test \

--proxy-user foo \

--conf spark.jars.packages=xxx \

/path/to/examples.jar \

Livy REST JSON协议

{
“className”: “org.apache.spark.examples.SparkPi”,

“jars”: [“a.jar”, “b.jar”],

“pyFiles”: [“a.py”, “b.py”],

“files”: [“foo.txt”, “bar.txt”],

“archives”: [“foo.zip”, “bar.tar”],


“driverMemory”: “10G”,

“driverCores”: 1,

“executorCores”: 3,

“executorMemory”: “20G”,

“name”: “test”,

“proxyUser”: “foo”,

}

-程序包。使用此命令时，将处理所有传递依赖项。

在Livy中，您需要转到解释器设置页面并在livy设置下添加新属性-

livy.spark.jars.packages

和值

com.databricks:spark-redshift_2.11:2.0.1

重新启动解释器，然后重试查询。
