I don't know, is it possible to have communism without corruption? But since He created our individualities differently :) I would presume that different people will have different things to do in Heaven. In addition, there is the matter of whatever specifically "Heavenly reward" entails. Whatever it is, it won't be a matter for jealousy, but just difference.
Re: If heaven will be communist -
I Corinthians 2:9-10
However, as it is written:
“What no eye has seen,
what no ear has heard,
and what no human mind has conceived”—
the things God has prepared for those who love him—
these are the things God has revealed to us by his Spirit.
The Spirit searches all things, even the deep things of God.
Communism is the imagined ideal society, where the greed has been eliminated by the fact that all means of production and goods are owned by everyone, and that no social inequality exists. Three is no money, no tax, no social difference. Everything that one could need is accessible to anyone at any time.
Once free from the basic human instinct of hoarding and ownership, social inequality, etc., crime, corruption and greed would disappear. How is that different from the imagined life in heaven? Both sound Utopian.

Same thing in communism; those who like to fish would fish; those who like to golf would golf. What will you do in heaven? Fish? Golf? You can't be serious!
In addition, there is the matter of whatever specifically "Heavenly reward" entails.
Your guess is as good as mine. :) But it's just a guess, regardless.
