Xiao Chen commented on HADOOP-13461: ------------------------------------ Thanks [~coheigea], could you fix the checkstyle? Other than that LGTM. Also, thanks Eddy and Akira for your help! > 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, 2.6.4 > Reporter: Colm O hEigeartaigh > Assignee: Colm O hEigeartaigh > Priority: Minor > Attachments: HADOOP-13461.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
