Subject [jira] [Created] (HDFS-8290) WebHDFS calls before namesystem initialization can cause NullPointerException.
Date Wed, 29 Apr 2015 21:54:07 GMT
Chris Nauroth created HDFS-8290:
-----------------------------------

             Summary: WebHDFS calls before namesystem initialization can cause NullPointerException.
                 Key: HDFS-8290
                 URL: https://issues.apache.org/jira/browse/HDFS-8290
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: webhdfs
    Affects Versions: 2.6.0
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
            Priority: Minor


The NameNode has a brief window of time when the HTTP server has been initialized, but the
namesystem has not been initialized.  During this window, a WebHDFS call can cause a {{NullPointerException}}.
 We can catch this condition and return a more meaningful error.
