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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
