Aaron T. Myers created HDFS-5403:
------------------------------------
Summary: WebHdfs client cannot communicate with older WebHdfs
servers post HDFS-5306
Key: HDFS-5403
URL: https://issues.apache.org/jira/browse/HDFS-5403
Project: Hadoop HDFS
Issue Type: Bug
Components: webhdfs
Affects Versions: 2.2.0
Reporter: Aaron T. Myers
Assignee: Aaron T. Myers
HDFS-5306 introduced the field infoSecurePort to the DatanodeIDProto PB
definition and made it optional for compatibility purposes. However, we don't
correctly the handle the case when this field is not present when deserializing
the response from a WebHdfs request. This results in an NPE at the client when
this occurs.
