> Time Spent: 2h 40m

> After the optimization in HADOOP-17079, {{JniBasedUnixGroupsNetgroupMapping}}
> does not implement {{getGroupSet}}.
> As a result, {{Groups.load()}} load the cache calling {{fetchGroupSet}}
> which got
> to the superclass {{JniBasedUnixGroupsMapping}}.
> In other words, the groups mapping will never fetch from {{NetgroupCache}}.
> This alters the behavior of the implementation. Is there a reason to bypass
> loading. CC: [~xyao]
