Subject [jira] [Created] (HADOOP-8167) Configuration deprecation logic breaks backwards compatibility
Date Tue, 13 Mar 2012 16:32:41 GMT
Configuration deprecation logic breaks backwards compatibility

                 Key: HADOOP-8167
                 URL: https://issues.apache.org/jira/browse/HADOOP-8167
             Project: Hadoop Common
          Issue Type: Bug
          Components: conf
    Affects Versions: 0.24.0, 0.23.3
            Reporter: Alejandro Abdelnur
            Assignee: Alejandro Abdelnur
            Priority: Blocker
             Fix For: 0.23.3

The deprecated Configuration logic works as follows:

For a dK deprecated key in favor of nK:

* on set(dK, V), it stores (nK,V)
* on get(dK) it does a reverseLookup of dK to nK and looks for get(nK)

While this works fine for single set/get operations, the iterator() method that returns an
iterator of all config key/values, returns only the new keys.

This breaks applications that did a set(dK, V) and expect, when iterating over the configuration
to find (dK, V).
