Juhong Park created SPARK-8863:
----------------------------------
Summary: 'spark_ec2.py' doesn't check '~/.aws/credentials' even if
boto can support '~/.aws/credentials'
Key: SPARK-8863
URL: https://issues.apache.org/jira/browse/SPARK-8863
Project: Spark
Issue Type: Improvement
Components: EC2
Affects Versions: 1.4.0
Reporter: Juhong Park
Priority: Minor
'spark_ec2.py' use boto to control ec2.
And boto can support '~/.aws/credentials' which is AWS CLI default
configuration file.
------------------From Ref of
Boto----------------------------------------------------------------
A boto config file is a text file formatted like an .ini configuration file
that specifies values for options that control the behavior of the boto
library. In Unix/Linux systems, on startup, the boto library looks for
configuration files in the following locations and in the following order:
/etc/boto.cfg - for site-wide settings that all users on this machine will use
(if profile is given) ~/.aws/credentials - for credentials shared between SDKs
(if profile is given) ~/.boto - for user-specific settings
~/.aws/credentials - for credentials shared between SDKs
~/.boto - for user-specific settings

* ref of boto: http://boto.readthedocs.org/en/latest/boto_config_tut.html
* ref of aws cli :
http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html
However 'spark_ec2.py' only check boto config & environment variable even if
there is '~/.aws/credentials', and 'spark_ec2.py' is terminated.
So I changed to check and use '~/.aws/credentials'.
