Query deb156b5-293e-472d-8897-5ee195b06b11, SUCCEEDED
https://eu-west-1.console.aws.amazon.com/athena/home?force&region=eu-west-1#query/history/deb156b5-293e-472d-8897-5ee195b06b11

Troubleshooting

Use the --debug option when launching the athena CLI to get AWS debug output:

$ athena --debug
2017-07-21 10:10:45,477 botocore.credentials [DEBUG] Looking for credentials via: env
2017-07-21 10:10:45,478 botocore.credentials [DEBUG] Looking for credentials via: assume-role
2017-07-21 10:10:45,478 botocore.credentials [DEBUG] Looking for credentials via: shared-credentials-file
2017-07-21 10:10:45,479 botocore.credentials [INFO] Found credentials in shared credentials file: ~/.aws/credentials
...

Turn on debug at the athena> prompt by typing:

athena> set debug true
debug - was: False
now: True

The below error means the version of aws CLI is not recent enough. Upgrade to version 1.10.18 or higher:

Command 'aws sts get-caller-identity --output text --query 'Account' --profile default' returned non-zero exit status 2

Command history is written to ~/.athena_history.
