Subject Re: Ambari 2.4 - custom service and condition package instalation
Date Tue, 17 Jan 2017 20:06:17 GMT
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?
