Reading from hdfs and writting to oracle 12 - apache-spark

Question

Hi.
I am trying to read from hdfs and write in oracle using pyspark, but I
have an error. I attach the code that I am using and the error that I
get:
pyspark --driver-class-path "/opt/oracle/app/oracle/product/12.1.0.2/dbhome_1/jdbc/lib/ojdbc7.jar"
from pyspark import SparkContext, SparkConf
from pyspark.sql import SQLContext, Row
conf = SparkConf().setAppName("myFirstApp").setMaster("local")
sc = SparkContext(conf=conf)
sqlContext = SQLContext(sc)
lines = sc.textFile("hdfs://bigdatalite.localdomain:8020/user/oracle/ACTIVITY/part-m-00000")
parts = lines.map(lambda l: l.split(","))
people = parts.map(lambda p: Row(name=p[0], age=p[1]))
schemaPeople = sqlContext.createDataFrame(people)
url = "jdbc:oracle:thin#localhost:1521/orcl"
properties = {
"user": "MOVIEDEMO",
"password": "welcome1",
"driver": "oracle.jdbc.driver.OracleDriver"
}
schemaPeople.write.jdbc(url=url, table="ACTIVITY", mode="append", properties=properties)
..and the error that show is:
Traceback (most recent call last):

Answer 1

Url should be specified in the "service" format, ie.
jdbc:oracle:thin:#//myhost:1521/orcl
