@SaranyaKatakam,

context variables must be pre-defined to be used in a job, although their value can be changed during run-time.Their value can also be passed into the job as a parameter when it starts.

globalMap variables can be defined during run-time - name and value - and need not exist at all to be used (will just be treated as null).  They cannot be passed into the job as a parameter when it starts.
