Todd Lipcon created HDFS-3490:
---------------------------------
Summary: DN WebHDFS methods throw NPE if Namenode RPC address
param not specified
Key: HDFS-3490
URL: https://issues.apache.org/jira/browse/HDFS-3490
Project: Hadoop HDFS
Issue Type: Bug
Components: data-node
Affects Versions: 2.0.0-alpha
Reporter: Todd Lipcon
Priority: Minor
Currently, there is no validation done on the NamenodeRpcAddressParam. If it is
not passed to the datanode webhdfs methods, an NPE will be generated trying to
use it. We should instead have some kind of validation on the parameter and
throw a more appropriate error message when it is missing.
