hftp throws NPE if security is not enabled on remote cluster ------------------------------------------------------------
Key: HDFS-2328 URL: https://issues.apache.org/jira/browse/HDFS-2328 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 0.20.205.0 Reporter: Daryn Sharp Priority: Critical Fix For: 0.20.205.0 If hftp cannot locate either a hdfs or hftp token in the ugi, it will call {{getDelegationToken}} to acquire one from the remote nn. This method may return a null {{Token}} if security is disabled(*) on the remote nn. Hftp will internally call its {{setDelegationToken}} which will throw a NPE when the token is {{null}}. (*) Actually, if any problem happens while acquiring the token it assumes security is disabled! However, it's a pre-existing issue beyond the scope of the token renewal changes. -- This message is automatically generated by JIRA.
