pyhive:使用pyhive设置单元属性

Question

我有一个复杂的蜂箱查询，它的底层连接是笛卡尔产品。所以我需要设置下面的属性。但是当我使用pyhive执行这些属性时，它无法执行。我要求为笛卡儿设置属性是一个错误。

hive.strict.checks.cartesian.product=false'''集set1 =‘

set2 =‘’SET hive.mapred.mode=‘’

def connectData(query,host,port,username):
    conn = hive.Connection(host=host, port=port, username=username).cursor()
    conn.execute(query)
    val=conn.fetchall()
    columnNames = [a[0] for a in  conn.description]
    df=pd.DataFrame(data=val,columns=columnNames)
    return df

def settings(query,host,port,username):
    conn = hive.Connection(host=host, port=port, username=username).cursor()
    conn.execute(query)

settings(set1, host, port, username)
settings(set2, host, port, username)

df = connectData(query, host, port, username)
print(df)

Answer 1

尝试如下所示的设置：

hive.connect('host', configuration={'hive.strict.checks.cartesian.product':'false'})
hive.connect('host', configuration={'hive.mapred.mode':'strict'})
