python - 如何使用 impyla 连接到 impala 或使用 pyhive 连接到 hive？

Question

我正在尝试使用带有此代码的 impyla 连接到 impala：

from impala.dbapi import connect
conn = connect(host='host_name.com', port=21050, user='usr', password='pass', use_ssl=True, auth_mechanism='LDAP')
cursor = conn.cursor()
cursor.execute('SHOW DATABASES')
cursor.fetchall()

根据文档，该库需要版本 0.2.1 中的 thrift_sasl 但我无法安装它，因为它显示此错误

当我安装最新版本的 thrift_sasl jupyter 时出现此错误：

AttributeError: 'TSSLSocket' object has no attribute 'isOpen'

我还尝试使用以下代码通过 pyhive 进行连接：

from pyhive import hive

host_name = "host_name.com"
port = 10000
user = "usr"
password = "pass"

def hiveconnection(host_name, port, user,password):
    conn = hive.Connection(host=host_name, port=port, username=user, password=password, auth='LDAP')
    cur = conn.cursor()
    cur.execute('SHOW DATABASES')
    result = cur.fetchall()

    return result

output = hiveconnection(host_name, port, user,password)
print(output)

它要我安装 sasl，但是当我尝试这样做时，它表明：

有任何想法吗？

在 2.7 版中使用 python 解决了这个问题。我认为兼容性存在问题。
