How do you connect to Kudu via PySpark

[#1]

Trying to create a dataframe like so

kuduOptions = {"kudu.master":"my.master.server", "kudu.table":"myTable"}

df = sqlContext.read.options(kuduOptions).kudu

The above code is a "port" of Scala code. Scala sample had kuduOptions defined as map.

I get an error stating "options expecting 1 parameter but was given 2"

How do you connect to Kudu via PySpark SQL Context?

@rams the error is correct as the syntax in pyspark varies from that of scala. 

For reference here are the steps that you'd need to query a kudu table in pyspark2

Create a kudu table using impala-shell

# impala-shell 

CREATE TABLE test_kudu (id BIGINT PRIMARY KEY, s STRING) 
PARTITION BY HASH(id) PARTITIONS 2 STORED AS KUDU; 
insert into test_kudu values (100, 'abc'); 
insert into test_kudu values (101, 'def'); 
insert into test_kudu values (102, 'ghi'); 

Launch pyspark2 with the artifacts and query the kudu table

# pyspark2 --packages org.apache.kudu:kudu-spark2_2.11:1.4.0

SparkSession available as 'spark'.

>>> kuduDF = spark.read.format('org.apache.kudu.spark.kudu').option('kudu.master',"nightly512-1.xxx.xxx.com:7051").option('kudu.table',"impala::default.test_kudu").load()

>>> kuduDF.show(3)

+---+---+
| id| s|
+---+---+
|100|abc|
|101|def|
|102|ghi|

For records, the same thing can be achieved using the following commands in spark2-shell

# spark2-shell --packages org.apache.kudu:kudu-spark2_2.11:1.4.0
