fiware - Python を使用した Fiware Cosmos Hive 接続

Question

次の Python コードを使用して、Hive クエリを Fiware Cosmos に送信しようとしています。

with pyhs2.connect(host='cosmos.lab.fiware.org',port=10000,
                                                authMechanism="PLAIN",
                                                user='xxx',
                                                password="xxx",
                                                database ="xxx" ) as conn: 

                    print ("pyhs --- %s seconds ---" % ( time.time() - start_time))
                    with conn.cursor() as cur:
                            print ("conn ok --- %s seconds ---" % ( time.time() - start_time))
                            cur.execute("add JAR /usr/local/apache-hive-0.13.0-bin/lib/json-serde-1.3.1-SNAPSHOT-jar-with-dependencies.jar")

しかし、私は次のエラーが発生します:

raceback (most recent call last):
File "script2.py", line 40, in <module>
database ="default" ) as conn: 
File "/usr/local/lib/python2.7/site-packages/pyhs2/__init__.py", line 7, in connect

buff = self.handle.recv(sz)
socket.error: [Errno 104] Connection reset by peer

2 か月前、同じコードで接続できました。変更または解決策はありますか？

前もって感謝します。
