 # Project Outline
 
 ## Create a Twitter Stream and send tweets to Spark
+We set up the Spark context in local mode with 3 CPU's running simulating 3 different machines. And build a Spark streaming context based on Spark context and set the time interval to 5 seconds. So the incoming tweets will be collect into 1 RDD every 5 seconds.
+
+conf = SparkConf().setMaster('local[3]')
+sc   = SparkContext(conf=conf)
+ssc  = StreamingContext(sc, 5)
+
+We build an app called TweetRead.py to pull tweet streaming from Twitter by using library called Tweepy and use socket to send streaming into Spark Streaming
+
+host = "localhost"      # Get local machine name
+port = 5555           # Reserve a port for your service.
+s = socket.socket()      # Create a socket object
+s.bind((host, port))        # Bind to the port
+s.listen(5)                 # Now wait for client connection.
+c, addr = s.accept()        # Establish connection with client.
+
+We use Streaming Context API socketTextStream to receive tweet Streaming through port and transfer into Dstreaming, which is the Streaming of RDD
+raw_tweets = ssc.socketTextStream('localhost',5555)
