That's another totally different problem.  You are trying to upgrade a running Jira.  The script tries to stop it, and fails for some reason.

You need to shut down a Jira to upgrade it.  You need to read the log file to find out why Jira has not shut down, and possibly forcibly kill it if necessary.

Checking if your instance of JIRA Software is running
Upgrade check list
Back up your external database
We strongly recommend you back up your JIRA Software database if you have
not already done so.

Please refer to the following URL for back up guidelines:
http://docs.atlassian.com/jira/jadm-docs-0710/Backing+up+data

Check plugin compatibility
Check that your non-bundled plugins are compatible with JIRA Software
7.10.2.

Access the plugin manager through the following URL:
http://localhost:8070/plugins/servlet/upm#compatibility

For more information see our documentation at the following URL:
http://docs.atlassian.com/jira/jadm-docs-0710/Upgrading+JIRA+applications

Please ensure you have read the above checklist before upgrading.
