ハイブに接続中にソケットエラーが発生しました：hiveserver2-client.py

Question

ハイブに接続しようとする前にこのエラーが発生したことがありますか？

使用するサンプルコード（https://github.com/telefonicaid/fiware-cygnus/blob/master/cygnus-ngsi/resources/hiveclients/python/hiveserver2-client.py）：

import sys 
import pyhs2 
from pyhs2.error import Pyhs2Exception 

# get the input parameters 
if len(sys.argv) != 6: 
    print 'Usage: python hiveserver2-client.py <hive_host> <hive_port> <db_name> <hadoop_user> <hadoop_password>' 
    sys.exit() 

hiveHost = sys.argv[1] 
hivePort = sys.argv[2] 
dbName = sys.argv[3] 
hadoopUser = sys.argv[4] 
hadoopPassword = sys.argv[5] 

# do the connection 
with pyhs2.connect(host=hiveHost, 
        port=hivePort, 
        authMechanism="PLAIN", 
        user=hadoopUser, 
        password=hadoopPassword, 
        database=dbName) as conn: 
    # get a client 
    with conn.cursor() as client: 
     # create a loop attending HiveQL queries 
     while (1): 
      query = raw_input('remotehive> ') 

      try: 
       if not query: 
        continue 

       if query == 'exit': 
        sys.exit() 

       # execute the query 
       client.execute(query) 

       # get the content 
       for row in client.fetch(): 
        print row 

      except Pyhs2Exception, ex: 
       print ex.errorMessage

あなたは、コードのあなたの作品を投稿することができますか？これは、いくつかの認証メカニズムまたは送信された資格情報が有効でないようです。

authMechanism= can be "PLAIN" or "KERBEROS"です。
