hawq stop cluster error
hello, when I execute 'hawq stop cluster', it goes wrong.
The error shows:

I tried to reinstall pygresql, but it still failed.
I am looking forward your reply. :)

Hi Kai,
This seems like pygresql install issue.
Are you using latest hawq? How do you reinstall pygresql?
Make sure you don't see any compile errors while making pygresql.
Thanks.
Regards,
Radar

Hi kai
It seems that you didn't source greenplum_path.sh in your {hawq-install-dir}.
You can also check PYTHONPATH environment variable, it should be '{hawq-install-dir}/lib/python:{other}'. And which version of python do you have installed?
