You can find all of the common and agent scripts located in site-packages of python. For example:
ls -l /usr/lib/python2.6/site-packages/ drwxr-xr-x 4 root root 4096 Feb 18 18:21 ambari_agent drwxr-xr-x 3 root root 4096 Feb 18 18:23 ambari_commons lrwxrwxrwx 1 root root 46 Feb 18 18:22 resource_management -> /usr/lib/ambari-server/lib/resource_management On Feb 18, 2015, at 2:27 PM, Yu, Tao <ta...@aware.com<mailto:ta...@aware.com>> wrote: Hi, Storm was supported starting from HDP 2.1. In storm.py (under /var/lib/ambari-server/resources/stacks/HDP/2.1/services/STORM/package/scripts), I noticed that it imports ambari_agent module. But couldn’t find where this ambari_agent module is. Does anyone know where this ambari_agent module located? Thanks, -Tao
