Python -将整数或字符串发送到Spark-Streaming

Question

我可以通过CSV文件发送我的数据。首先，将我的随机数写入CSV文件，然后发送它，但是可以直接发送它吗？我的套接字代码：

import socket
host = 'localhost'
port = 8080

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host, port))
s.listen(1)
while True:
    print('\nListening for a client at',host , port)
    conn, addr = s.accept()
    print('\nConnected by', addr)
    try:
        print('\nReading file...\n')
        while 1:
            out = "test01"
            print('Sending line', line)
            conn.send(out)
    except socket.error:
        print ('Error Occured.\n\nClient disconnected.\n')
conn.close()

spark streaming代码：

from pyspark import SparkContext
from pyspark.streaming import StreamingContext

sc = SparkContext("local[2]","deneme")
ssc = StreamingContext(sc, 10)
socket_stream = ssc.socketTextStream("localhost",8080)

random_integers = socket_stream.window( 30 )

digits = random_integers.flatMap(lambda line: line.split(" ")).map(lambda digit: (digit, 1))

digit_count = digits.reduceByKey(lambda x,y:x+y)
digit_count.pprint()

ssc.start()
