The data 'MYD11A2' is not explicitly supported by SNAP nor by BEAM.
Maybe it is read generically by the NetCDF library.
You can try to open it in the desktop application and open the information window. There it should be stated with which reader the file was read.
If you just want to convert the file into a different format you can simply use the pconvert tool.
It is located in the
bin folder of the SNAP installation directory.
pconvert -h to get usage information
