Subject [jira] [Updated] (HADOOP-7425) ReflectionUtils.setConf would configure anything Configurable twice
Date Mon, 20 Feb 2012 11:45:34 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7425?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

steven zhuang updated HADOOP-7425:
----------------------------------

    Affects Version/s: 0.20.2
                       0.20.205.0
               Status: Patch Available  (was: Open)

so glad this problem is updated.
and Robert, I think the given patch might not point out how the problem is gonna happen. the
tested object should be an object from a class implements these two interfaces: Configurable,
JobConfigurable, only in this case will the object be configured twice(1. setConf and 2. configure).

> In  the setConf method of org.apache.hadoop.util.ReflectionUtils, any instance of Configurable
would be configured twice.
> In 0.21.0, KeyFieldBasedPartitioner implements the Configurable interface. When configured
twice, it get two KeyDescription and gives out wrong partition number. 
> public static void setConf(Object theObject, Configuration conf) {
>     if (conf != null) {
>       if (theObject instanceof Configurable) {
>         ((Configurable) theObject).setConf(conf);
>       }
>       setJobConf(theObject, conf);
>     }
>   }
