Suresh Srinivas commented on HDFS-4362: --------------------------------------- bq. This patch appears to allow protobuf token requests to return null, correct? Yes. Before this patch, null could not be returned by the server. Even if null is returned by the server, client could not handle that response and would have encountered a protobuf exception. > GetDelegationTokenResponseProto does not handle null token > ---------------------------------------------------------- > > Key: HDFS-4362 > URL: https://issues.apache.org/jira/browse/HDFS-4362 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.0.2-alpha > Reporter: Suresh Srinivas > Assignee: Suresh Srinivas > Priority: Critical > Fix For: 2.0.3-alpha > > Attachments: HDFS-4362.patch > > > While working on HADOOP-9173, I notice that the > GetDelegationTokenResponseProto declares the token field as required. However > return of null token is to be expected both as defined in > FileSystem#getDelegationToken() and also based on HDFS implementation. This > jira intends to make the field as optional. -- This message is automatically generated by JIRA.
