I am new to Spark Streaming. Using PySpark in PyCharm I am unable to get passed the socketTextStream initialization.
def start_streaming (self):
sp = SparkContext('local[2]', 'streamingTest')
stream = StreamingContext(sp, 1)
**items = stream.socketTextStream('localhost', '9009')**
print(items)
lines = items.flatMap(lambda line : line.split('\n'))
I am receiving the following error. Any ideas on what the problem is?
