Major Description
I am facing a troubling issue when i submit my spark job with livy. This is the spark code which i am submitting.
raw_df = spark.read.format("jdbc")\
.option("url", url)\
.option("query", query)\
.option("user", user)\
.option("password", pass)\
.option("numPartitions", 4)\
.option("driver", "com.microsoft.sqlserver.jdbc.SQLServerDriver")\
.load()
This code is running fine perfectly with normal spark submit. But i want to submit this job via livy . This is payload i am passing for post request
payload =
{ "queue": "default", "name": "appname", "proxyUser": "hadoop", "conf":\{"spark.jars.packages": "com.microsoft.sqlserver:mssql-jdbc:7.2.1.jre8"},
"file": "s3://dbbucket/emrbuilds/app/src/main_pull.py",
"args":["2020-10-10"]
}
But i am getting java nullpointer execption
