>   interface HedgedRead {
>     String  THRESHOLD_MILLIS_KEY = PREFIX + "threshold.millis";
>     long    THRESHOLD_MILLIS_DEFAULT = 500;
>     String  THREADPOOL_SIZE_KEY = PREFIX + "threadpool.size";
>     int     THREADPOOL_SIZE_DEFAULT = 0;
>   }
> {code}
> {{PREFIX}} is not defined in the interface, so "dfs.client" is used as {{PREFIX}}. Therefore,
the properties are "dfs.client.threshold.millis" and "dfs.client.threadpool.size". They should
be "dfs.client.hedged.read.threshold.millis" and "dfs.client.hedged.read.threadpool.size".
