[jira] [Updated] (HADOOP-7425) ReflectionUtils.setConf would
configure anything Configurable twice
[ https://issues.apache.org/jira/browse/HADOOP-7425?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
steven zhuang updated HADOOP-7425:
----------------------------------
Description:
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);
}
}
was:
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.

}
setJobConf(theObject, conf);
}
}
Summary: ReflectionUtils.setConf would configure anything Configurable twice (was: ReflectionUtils.setConf would configure the KeyFieldBasedPartitioner twice in Hadoop 0.21.0, when KeyFieldBasedPartitioner is an Configurable instance)
