连接到配置文件下的区域时出错

Question

As per document region is also a parameter of boto.emr.EmrConnection class however, I get the follwoing error while making the connection: conn = boto.emr.EmrConnection(profile_name='profile_name', region='us-west-2')

File "C:\\Python27\\lib\\site-packages\\boto-2.38.0-py2.7.egg\\boto\\emr\\connection.py", line 68, in init self.region.endpoint, debug, AttributeError: 'str' object has no attribute 'endpoint'

Any idea?

Answer 1

The method is expecting RegionInfo type for region, not string.

So pass boto.ec2.get_region('us-west-2') instead of 'us-west-2'

import boto.ec2
boto.emr.EmrConnection(profile_name='profile_name', region=boto.ec2.get_region('us-west-2'))

Answer 2

The method expects RegionInfo so try:

import boto.emr
conn = boto.emr.connect_to_region('us-west-1')
