Currently the onDemand Jira use Subversion and require issue key on each commit.
After moving to GIT, how can I get this feature on with Bitbucket.
Currently user can push without any issue key.
Subversion was most likely configured with a pre-commit hook. Commits happen locally before the push. So, to accomplish this, you want a pre-commit hook on Git installed locally.

Each user would need this. Optimially, you'd create a Git installation package for your team that they all use.
