Athena CLI ========== [](https://travis-ci.org/guardian/athena-cli) Presto-like CLI tool for [AWS Athena](https://aws.amazon.com/athena/). The alternative is using the AWS CLI [Athena sub-commands](http://docs.aws.amazon.com/cli/latest/reference/athena/). [](https://asciinema.org/a/132545) Requirements ------------ A recent version of the `aws` CLI must be available on the PATH. Installation ------------ To install using `pip` run: $ pip install athena-cli Or, clone the GitHub repo and run: $ python setup.py install Configuration ------------- Only required configuration is AWS credentials. Usage ----- ``` $ athena --help usage: athena [--debug] [--execute <statement>] [--output-format <format>] [--schema <schema>] [--profile <profile>] [--region <region>] [--s3-bucket <bucket>] [--server-side-encryption] [--version] Athena interactive console optional arguments: -h, --help show this help message and exit --debug enable debug mode --execute STATEMENT execute statement in batch mode --output-format FORMAT output format for batch mode [ALIGNED, VERTICAL, CSV, TSV, CSV_HEADER, TSV_HEADER, NULL] --schema SCHEMA, --database SCHEMA, --db SCHEMA default schema --profile PROFILE AWS profile --region REGION AWS region --s3-bucket BUCKET, --bucket BUCKET AWS S3 bucket for query results --server-side-encryption, --encryption Use server-side-encryption for query results --version show version info and exit ``` ``` athena> help Supported commands: QUIT SELECT ALTER DATABASE <schema> ALTER TABLE <table> CREATE DATABASE <schema> CREATE TABLE <table> DESCRIBE <table> DROP DATABASE <schema> DROP TABLE <table> MSCK REPAIR TABLE <table> SHOW COLUMNS FROM <table> SHOW CREATE TABLE <table> SHOW DATABASES [LIKE <pattern>] SHOW PARTITIONS <table> SHOW TABLES [IN <schema>] [<pattern>] SHOW TBLPROPERTIES <table> USE [<catalog>.]<schema> VALUES row [, ...] ``` See http://docs.aws.amazon.com/athena/latest/ug/language-reference.html Example ------- ``` athena> use sampledb; athena:sampledb> show tables; tab_name ------------ elb_logs (1 rows) Query deb156b5-293e-472d-8897-5ee195b06b11, SUCCEEDED https://eu-west-1.console.aws.amazon.com/athena/home?force®ion=eu-west-1#query/history/deb156b5-293e-472d-8897-5ee195b06b11 Time: 0:00:00, CPU Time: 474ms total, Data Scanned: 0.00B, Cost: $0.00 ``` Troubleshooting --------------- Use the `--debug` option when launching the `athena` CLI to get AWS debug output: ```shell $ 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`.
