Thanks for the response. I wanted to know if the memory assignment could be done, without providing these while submitting jobs.
@Phoncy Joseph There are only 3 ways as of now:
- Global configs which are in mapred-site.xml
- Passing through command line while submitting the job
- Hardcode in the code(although this is not dynamic).
@Phoncy Joseph You're welcome. Feel free to accept the answer if this helps you.
