[jira] [Created] (HADOOP-11454) Potential null dereference in Configuration#loadProperty()

Ted Yu created HADOOP-11454:
-------------------------------

             Summary: Potential null dereference in Configuration#loadProperty()
                 Key: HADOOP-11454
                 URL: https://issues.apache.org/jira/browse/HADOOP-11454
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Ted Yu
            Assignee: Ted Yu


Here is related code:
{code}
2581             properties.setProperty(attr, value);
2582             updatingResource.put(attr, source);
2583           } else if (!value.equals(properties.getProperty(attr))) {
{code}
The null check in the enclosing if statement is accompanied with allowNullValueProperties, thus dereferencing value above may result in NPE.
