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.
