[jira] [Created] (HADOOP-13461) NPE in KeyProvider.rollNewVersion

Colm O hEigeartaigh created HADOOP-13461:
--------------------------------------------

             Summary: NPE in KeyProvider.rollNewVersion
                 Key: HADOOP-13461
                 URL: https://issues.apache.org/jira/browse/HADOOP-13461
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.7.2
            Reporter: Colm O hEigeartaigh
            Priority: Minor
             Fix For: 2.8.0, 2.7.3, 2.6.5, 3.0.0-alpha1


When KeyProvider.rollNewVersion(String name) is called, it first gets the metadata for the given name. The javadoc states that the getMetadata(String name) method can return null if the key doesn't exist. However rollNewVersion throws a NPE if the returned metadata is null.
