> After HDFS-14743, every authorization check logs a messages like the following
> {noformat}
> 2020-04-07 23:44:55,276 INFO org.apache.hadoop.security.UserGroupInformation: Default authorization provider supports the new authorization provider API
> 2020-04-07 23:44:55,276 INFO org.apache.hadoop.security.UserGroupInformation: Default authorization provider supports the new authorization provider API
> 2020-04-07 23:44:55,277 INFO org.apache.hadoop.security.UserGroupInformation: Default authorization provider supports the new authorization provider API
> 2020-04-07 23:44:55,278 INFO org.apache.hadoop.security.UserGroupInformation: Default authorization provider supports the new authorization provider API
> {noformat}
> The intend was to check for authorization provider's API compatibility during initialization but apparently it's not. This will result in serious performance regression.
