> In our production environment, the standby NN often do fullgc, through mat we found the
largest object is FileSystem$Cache, which contains 7,844,890 DistributedFileSystem.
> By view hierarchy of method FileSystem.get() , I found only NamenodeWebHdfsMethods#get
call FileSystem.get(). I don't know why creating different DistributedFileSystem every time
instead of get a FileSystem from cache.
> {code:java}
>     case GETHOMEDIRECTORY: {
>       final String js = JsonUtil.toJsonString("Path",
>           FileSystem.get(conf != null ? conf : new Configuration())
>               .getHomeDirectory().toUri().getPath());
>       return Response.ok(js).type(MediaType.APPLICATION_JSON).build();
>     }
> {code}
> When we close FileSystem when GETHOMEDIRECTORY, NN don't do fullgc.
> {code:java}
>     case GETHOMEDIRECTORY: {
>       FileSystem fs = null;
>       try {
>         fs = FileSystem.get(conf != null ? conf : new Configuration());
>         final String js = JsonUtil.toJsonString("Path",
