shanyu zhao updated HADOOP-10178:
---------------------------------
Attachment: HADOOP-10178-v2.patch
Add getAlternativeNames() method to get the non-deprecated alias of a given
non-deprecated key. When set a non-deprecated key, we need to check if it has
any alias (that deprecate the same key) non-deprecated keys and set those
properties as well.
> Configuration deprecation always emit "deprecated" warnings when a new key is
> used

> Even if you use any new configuration properties, you still find "deprecated"
> warnings in your logs. E.g.:
> 13/12/14 01:00:51 INFO Configuration.deprecation: mapred.input.dir.recursive
> is deprecated. Instead, use
> mapreduce.input.fileinputformat.input.dir.recursive
