--------------------------------------------
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.
