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
