when I load rgdal and GdalUtils packages to read hdf4 file, with the following
library(raster)
library(raster)
library(sp)
library(rgdal)
library(proj4)
library(gdalUtils)`
it gives the following warning message
rgdal: version: 1.2-12, (SVN revision 681)
Geospatial Data Abstraction Library extensions to R successfully loaded

Afterwards I tried the following
file<-"D:\\sample_lst\\MOD11A2.A2000089.h21v07.006.2015058064314.hdf"
sds<-get_subdatasets(file)
It begin extremely busy, just returns nothing
Even I have tried the following
library("gdalUtils")
gdal_setInstallation(verbose=TRUE)
getOption("gdalUtils_gdalPath")
but takes a lot of time scanning file pathes.
Is there anybody who can help me to read subdatasets and gdalinfo
