    环境:Centos6.5 python2.7

    1、下载并安装Python package:impyla-0.14.0.tar.gz

    https://pypi.python.org/packages/6c/30/da9fe733561eb948a07aaef3ae0240ac6a5466cfea5e6872525515634544/impyla-0.14.0.tar.gz

    python setup.py install
    或者pip install impyla

    2、python客户端与impala交互

    连接impala:部署的ip--hive,默认端口:21050

    from impala.dbapi import connect
    conn = connect(host='192.168.0.10', port=21050)
    cur = conn.cursor()
    cur.execute('select name as num from user ;')
    data_list=cur.fetchall()
    for data in data_list:
        #用户列表
       print "用户名称:",data
