I followed http://docs.openstack.org/icehouse/install-guide/install/apt/content/heat-install.html (here) to install heat (Icehouse). When creating DB tables, the error appeared, as follows.

root@controller:~# su -s /bin/sh -c "heat-manage db_sync" heat No handlers could be found for logger "heat.common.config" 2014-11-17 21:51:58.596 8685 WARNING heat.openstack.common.db.sqlalchemy.session [-] This application has not enabled MySQL traditional mode, which means silent data corruption may occur.

Mysql version is 14.14 Distrib 5.5.40, for debian-linux-gnu (x86_64) using readline 6.2.

I only found https://bugs.launchpad.net/heat/+bug/1316646 (this bug), but it doesn't seem to be same with my problem. Doesn't Icehouse heat support mysql? Should I use another database for heat? Thanks.
