The following example shows how to create an interactive session, submit a statement, and retrieve the result of the statement; the return ID could be used for further queries. When is a closeable question also a “very low quality” question? ``application/json``, the value is a JSON value.
need to specify code kind (spark, pyspark, sparkr or sql) during statement submission. The spark job parameters is in JSON format. * Going to implement submit Spark jobs through Livy Services.

12:00 AM, @sshao am submitting spark job through livy , below are my conf parameters, data = {'kind': 'pyspark','driverMemory':'2G','driverCores':2,'numExecutors': 1, 'executorMemory': '1G','executorCores':1,'conf':{'spark.yarn.appMasterEnv.PYSPARK_PYTHON':'/usr/bin/python3'}}. The “application-jar” should be reachable by remote cluster manager, which means this “application-jar” should be put onto a distributed file system like HDFS.
