配置单元-python连接错误

Question

这是代码：

#!/usr/bin/env python
import pyhs2
try:
with pyhs2.connect(host='localhost',
           port=10001,
           authMechanism="PLAIN",
           user='root',
           password='test',
           database='test') as conn:
    with conn.cursor() as cur:
        #Show databases
        print cur.getDatabases()
        #Execute query
        cur.execute("select * from raw_stats")
        #Return column info from query
        print cur.getSchema()
        #Fetch table results
        for i in cur.fetch():
            print i
except Thrift.TException, tx:
print '%s' % (tx.message)
