[jira] [Created] (HDFS-15271) Update DFSUtil.getSpnegoKeytabKey based on hadoop.http.authentication.kerberos.keytab

Masatake Iwasaki created HDFS-15271:
---------------------------------------

             Summary: Update DFSUtil.getSpnegoKeytabKey based on hadoop.http.authentication.kerberos.keytab
                 Key: HDFS-15271
                 URL: https://issues.apache.org/jira/browse/HDFS-15271
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: security
    Affects Versions: 3.3.0
            Reporter: Masatake Iwasaki
            Assignee: Masatake Iwasaki


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.
