title: Python script to inject bulks into KairosDB - only 1st bulk inserted, the rest ignored
body: <p>I wrote the following script that allows me to set the amount of sensors and the amount of bulk inserts for them.
  Each bulk insert gets a different epoch time.
  Each sensor insert gets a different value  + different tag (temp) value.</p>
  
  <p><em>Kairos version:</em></p>
  
  <pre><code>root@ip-172-16-0-147:~# echo "version" | nc -w 30 localhost 4242
  KairosDB 1.2.0-0.3beta.20171211170411
  </code></pre>
  
  <p><em>Scylla (Backend Storage) version:</em></p>
  
  <pre><code>[centos@ip-172-16-0-128 ~]$ scylla --version
  2.0.2-0.20171201.07b039f
  </code></pre>
  
  <p><strong>The problem:</strong>
  Only the 1st bulk is inserted into Kairos, the other bulks are just ignored and I can't figure out why.
  Any ideas as to why, or how to correct the script are appreciated.</p>
  
  <p><strong>The script:</strong></p>
  
  <pre><code>import socket
  import time
  import random
  
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  s.connect(("[Kairos_IP]", 4242))
  
  start_time = time.time()
  lowerRange = 1
  upperRange = 5
  sensor_amount = 10
  sensors = []
  for x in range(lowerRange, upperRange):
      str=""
      curr_epoch = time.time()
      #curr_epoch = int(time.time() * 1000)
      time.sleep(1)
      for y in range(1,sensor_amount):
          statement = "put SENSOR_%d %d %d temp=%d\n" %(y,curr_epoch,random.randint(1,500),random.randint(1,500))
          sensors.append(statement)
          str+=(sensors[y-1])
          print statement
          s.send(str)
      print curr_epoch
  
  print("--- %s seconds ---" % (time.time() - start_time))
