Hi, I would like to ask if it is currently possible to use spark-ec2 script together with credentials that are consisting not only from: aws_access_key_id and aws_secret_access_key, but it also contains aws_security_token. When I try to run the script I am getting following error message: ERROR:boto:Caught exception reading instance data Traceback (most recent call last): File "/Users/zikes/opensource/spark/ec2/lib/boto-2.34.0/boto/utils.py", line 210, in retry_url r = opener.open(req, timeout=timeout) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 404, in open response = self._open(req, data) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 422, in _open '_open', req) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 382, in _call_chain result = func(*args) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 1214, in http_open return self.do_open(httplib.HTTPConnection, req) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 1184, in do_open raise URLError(err) URLError: <urlopen error [Errno 64] Host is down> ERROR:boto:Unable to read instance data, giving up No handler was ready to authenticate. 1 handlers were checked. ['QuerySignatureV2AuthHandler'] Check your credentials Does anyone has some idea what can be possibly wrong? Is aws_security_token the problem? I know that it seems more like a boto problem, but still I would like to ask if anybody has some experience with this? My launch command is: ./spark-ec2 -k my_key -i my_key.pem --additional-tags "mytag:tag1,mytag2:tag2" --instance-profile-name "profile1" -s 1 launch test Thank you in advance for any help.
