Win10,64bit系统，python连接hive，安装impyla依赖包

创建于：20200802
修改于：20200802

1、环境介绍

win10 64bit
python3.6.6 （conda建立的虚拟环境）

2、基本安装过程

下面是基本的安装过程，具体参照官网：
cloudera/impyla

我在PyCharm的Terminal下安装的。如pip install six

six
bit_array
thriftpy
#这样不依赖Microsoft Visual C++ 14.0
thrift_sasl==0.2.1 --no-deps
#这样不依赖Microsoft Visual C++ 14.0
pure-sasl
impyla

3、报错信息及解决办法

错误信息 error: Microsoft Visual C++ 14.0 is required. Get it with “Microsoft Visual C++ Build Tools”: http://landinghub.visualstudio.com/visual-cpp-build-tools

解决方案1 在windows下安装Visual Studio

解决方案2直接下载二进制安装包进行安装
二进制安装包下载地址：https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python

下载对应的whl文件:cp后面是python版本，amd64代表64位，点击s所需版本的whl文件下载。如下图。
使用 pip install 下载文件的完整路径名，进行安装。

进入whl所在文件夹，地址栏输入cmd；
或者
在conda prompt （以管理员身份打开）进入到相应的目录（这对于安装conda虚拟环境的适用）

比如： pip install C:\Users\jc\Desktop\Twisted-18.4.0-cp36-cp36m-win_amd64.whl

4、python链接impala

# python 3.6.6
from impala.dbapi import connect

def connect(host='localhost', port=21050, database=None, timeout=None,
            use_ssl=False, ca_cert=None, auth_mechanism='NOSASL', user=None,
            password=None, kerberos_service_name='impala', use_ldap=None,
            ldap_user=None, ldap_password=None, use_kerberos=None,
            protocol=None, krb_host=None, use_http_transport=False,
            http_path=''):
    """Get a connection to HiveServer2 (HS2).

    These options are largely compatible with the impala-shell command line
    arguments. See those docs for more information.

    Parameters
    ----------
    host : str
        The hostname for HS2. For Impala, this can be any of the `impalad`s.
    port : int, optional
        The port number for HS2. The Impala default is 21050. The Hive port is
        likely different.
    database : str, optional
        The default database. If `None`, the result is
        implementation-dependent.
    timeout : int, optional
        Connection timeout in seconds. Default is no timeout.
    use_ssl : bool, optional
        Enable SSL.
    ca_cert : str, optional
        Local path to the the third-party CA certificate. If SSL is enabled but
        the certificate is not specified, the server certificate will not be
        validated.
    auth_mechanism : {'NOSASL', 'PLAIN', 'GSSAPI', 'LDAP'}
        Specify the authentication mechanism. `'NOSASL'` for unsecured Impala.
        `'PLAIN'` for unsecured Hive (because Hive requires the SASL
        transport). `'GSSAPI'` for Kerberos and `'LDAP'` for Kerberos with
        LDAP.
    user : str, optional
        LDAP user, if applicable.
    password : str, optional
        LDAP password, if applicable.
    kerberos_service_name : str, optional
        Authenticate to a particular `impalad` service principal. Uses
        `'impala'` by default.
    use_ldap : bool, optional
        Specify `auth_mechanism='LDAP'` instead.

        .. deprecated:: 0.11.0
    ldap_user : str, optional
        Use `user` parameter instead.

        .. deprecated:: 0.11.0
    ldap_password : str, optional
        Use `password` parameter instead.

        .. deprecated:: 0.11.0
    use_kerberos : bool, optional
        Specify `auth_mechanism='GSSAPI'` instead.

        .. deprecated:: 0.11.0
    protocol : str, optional
        Do not use.  HiveServer2 is the only protocol currently supported.

        .. deprecated:: 0.11.0


    Returns
    -------
    HiveServer2Connection
        A `Connection` object (DB API 2.0-compliant).
    """
