Masatake Iwasaki updated HDFS-15271:
------------------------------------
    Description: After HADOOP-16354, 
{{hadoop.http.authentication.kerberos.(principal|keytab)}} obsoleted 
{{dfs.web.authentication.kerberos.(principal|keytab)}}.  (was: After 
HADOOP-16314, setting {{dfs.web.authentication.kerberos.keytab}} has no effect. 
Keytab file can be specified by {{hadoop.http.authentication.kerberos.keytab}} 
now. DFSUtil.getSpnegoKeytabKey should care about the new proeperty while 
keeping backward compatibility. Since the {{getSpnegoKeytabKey}} is only called 
by NameNodeHttpServer and the value is not used, deprecating it could be an 
option.)

> Remove obsolete SPNEGO configuration of NN, SNN and JN.
