Configuration deprecation mechanism doesn't work properly for GenericOptionsParser/Tools ----------------------------------------------------------------------------------------
Key: HADOOP-7287 URL: https://issues.apache.org/jira/browse/HADOOP-7287 Project: Hadoop Common Issue Type: Bug Components: conf Affects Versions: 0.22.0 Reporter: Todd Lipcon Priority: Blocker Fix For: 0.22.0 Attachments: hadoop-7287-testcase.txt For example, you can't use -D options on the "hadoop fs" command line in order to specify the deprecated names of configuration options. The issue is that the ordering is: - JVM starts - GenericOptionsParser creates a Configuration object and calls set() for each of the options specified on command line - DistributedFileSystem or other class eventually instantiates HdfsConfiguration which adds the deprecations - Some class calls conf.get("new key") and sees the default instead of the version set on the command line -- This message is automatically generated by JIRA.
