> Key: HDFS-5279
> URL: https://issues.apache.org/jira/browse/HDFS-5279
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 3.0.0, 2.1.1-beta
> Reporter: Chris Nauroth
> Assignee: Chris Nauroth
> Attachments: HDFS-5279.1.patch, HDFS-5279.2.patch
>
>
> HDFS-4372 added tracking of NameNode startup progress. As part of that
> change, the NameNode HTTP server now starts before initialization of the
> {{FSNamesystem}}. There are a few code paths remaining in the JSP pages that
> are at risk of causing {{NullPointerException}} if accessed when the
> {{FSNamesystem}} has not been fully initialized.
