{noformat}
+ String httpKeytabKey =
DFSConfigKeys.DFS_WEB_AUTHENTICATION_KERBEROS_KEYTAB_KEY;
+ if (httpKeytabKey == null) {
+ httpKeytabKey = DFSConfigKeys.DFS_NAMENODE_KEYTAB_FILE_KEY;
+ }
{noformat}
Should null check be {{conf.get(httpKeytabKey) == null}}?
> namenode http server should use the web authentication keytab for spnego
