Question

此处详细信息：

shell中的所有内容都没问题，但是当我尝试使用python连接hive时抛出这些错误......

使用版本
  Hadoop 2.7.X

Hive 2.1.X

Python 2.6   Mongo Hadoop连接器

    import pyhs2

    with pyhs2.connect(host='hadoop-master',
                   port=10000,
                   authMechanism="PLAIN",
                   user='hadoop_user',
                   password='iudev',
                   database='default'
                   ) as conn:
        with conn.cursor() as cur:
            #Show databases
            print cur.getDatabases()

            #Execute query
            cur.execute("select * from table")

            #Return column info from query
            print cur.getSchema()

            #Fetch table results
            for i in cur.fetch():
            print i

hiveServer2正在运行

终端错误
