mass and field

[sidharath]

Is the gravitational field according to general theory of relativity independent of mass

I'm not sure what you're asking. You can have gravitational waves in a vacuum, similar to how electromagnetic waves can exist far away from any charges.

No. GR and Newtonian gravity are the same in most applications, and depend on mass. GR recognizes this as depending on energy, and mass is a form of energy.
