Using pyspark to connect to PostgreSQL

Question

I am trying to connect to a database with pyspark and I am using the following code:

sqlctx = SQLContext(sc)
df = sqlctx.load(
    url = "jdbc:postgresql         


        

Answer 1

Just initialize pyspark with --jars

E.g.: pyspark --jars /path/Downloads/postgresql-42.2.16.jar

then create a dataframe as suggested above in other answers

E.g.:

df2 = spark.read.format("jdbc").option("url", "jdbc:postgresql://localhost:5432/db").option("dbtable", "yourTableHere").option("user", "postgres").option("password", "postgres").option("driver", "org.postgresql.Driver").load()
