FAQ
spellcheck for configuration
----------------------------

Key: HADOOP-7036
URL: https://issues.apache.org/jira/browse/HADOOP-7036
Project: Hadoop Common
Issue Type: New Feature
Components: conf
Reporter: Ari Rabkin
Assignee: Ari Rabkin


Hadoop does fairly limited correctness checks of its configuration. I propose a "configuration spellcheck" that can automatically catch errors, and particularly can catch cases where users mis-type the name of an option.

The system works as follows:

- Use program analysis to extract the set of options supported by each Hadoop version, annotated when possible with their types into a 'dictionary file'.
- Distribute these extracted sets, per version.
- A script that reads a dictionary file, reads the Hadoop config from a specified directory, and reports deviations. In particular, the system can report when an option is set that Hadoop will never read or when an invalid value is specified.
