Jing Zhao created HADOOP-9735: --------------------------------- Summary: Deprecated configuration property can overwrite non-deprecated property Key: HADOOP-9735 URL: https://issues.apache.org/jira/browse/HADOOP-9735 Project: Hadoop Common Issue Type: Bug Affects Versions: 3.0.0, 2.1.0-beta Reporter: Jing Zhao Assignee: Jing Zhao Priority: Minor Attachments: deprecated-conf.test.patch
For the current Configuration implementation, if a conf file contains definitions for both a non-deprecated property and its corresponding deprecated property (e.g., fs.defaultFS and fs.default.name), the latter will overwrite the previous one. In the fs.defaultFS example, this may cause client failover not work. It may be better to keep the non-deprecated property's value unchanged. In the meanwhile, Configuration#getPropertySources may return wrong source information for a deprecated property. E.g., after setting fs.defaultFS, Configuration#getPropertySources("fs.default.name") will return "because fs.defaultFS is deprecated". -- This message is automatically generated by JIRA.
