> In HFileSystem
> {code}
>     // Create the default filesystem with checksum verification switched on.
>     // By default, any operation to this FilterFileSystem occurs on
>     // the underlying filesystem that has checksums switched on.
>     this.fs = FileSystem.get(conf);
>     this.useHBaseChecksum = useHBaseChecksum;
>     fs.initialize(getDefaultUri(conf), conf);
> {code}
> We call fs.initialize(). Generally the FS would have been created and inited either in the FileSystem.get() call above or even when we try to check 
> {code}
>   FileSystem fs = p.getFileSystem(c);
> {code}
> The FS that gets cached in the hadoop-common layer does the init for us. So we doing it again is redundant.
