Hmm, my workaround works until i try upgrade HDP stack. There is another hard coded package. I'll investigate it more Tomorrow but now it looks like big race condition - I am not able to specify deb package per component without changing ambari server and agent code. This was more clear in 2.2 version.
Am i only one who need more control on installed package in custom service?
