This is a generic JDBC write to a DB from Pyspark
def writeTableWithJDBC(dataFrame, url, tableName, user, password, driver,
mode):
try:
dataFrame. \
write. \
format("jdbc"). \
option("url", url). \
option("dbtable", tableName). \
option("user", user). \
option("password", password). \
option("driver", driver). \
mode(mode). \
save()
except Exception as e:
print(f"""{e}, quitting""")
sys.exit(1)
Example
url = "jdbc:hive2://" + config['hiveVariables']['hiveHost'] + ':' +
config['hiveVariables']['hivePort'] + '/default'
driver= "com.cloudera.hive.jdbc41.HS2Driver"
Note the correct driver
