HttpServer2#setSecurityEnabled

[Prabhu Joseph]

Hi,

    Have observed in multiple places HttpServer2#setSecurityEnabled is set
using hadoop.security.authentication value instead of
hadoop.http.security.authentication.
This will make HttpServer2 to do initSpnego and initilaize
AuthenticationFilter with type
kerberos. I think we should use hadoop.http.authentication.type instead of
UserGroupInformation.isSecurityEnabled. Please correct me if I am wrong.

Thanks,
Prabhu Joseph

HttpServer2.Builder builder = new HttpServer2.Builder().setName(name)
    .setConf(conf).setACL(new AccessControlList(conf.get(DFS_ADMIN, " ")))
    .setSecurityEnabled(UserGroupInformation.isSecurityEnabled())
    .setUsernameConfKey(spnegoUserNameKey)
    .setKeytabConfKey(getSpnegoKeytabKey(conf, spnegoKeytabFileKey));


*org.apache.hadoop.yarn.webapp.WebApps*

if (hasSpnegoConf) {
  builder.setUsernameConfKey(spnegoPrincipalKey)
      .setKeytabConfKey(spnegoKeytabKey)
      .setSecurityEnabled(UserGroupInformation.isSecurityEnabled());
}
