Subject Re: Bypass software install on hosts
Date Thu, 30 Apr 2015 22:53:39 GMT
https://issues.apache.org/jira/browse/AMBARI-10386 tracked a similar issue. The idea is to
introduce a flag that tells the agent that host is prepped and thus skip some operations.
The current implementation is a all or nothing approach. Based on what you say, we need levels
of host/cluster readiness. PACKAGES_INSTALLED = True means skip installing binaries. FILESYSTEM_PREPPED
means that there is an externally populated HCFS thus Ambari should not try to copy jars etc.

I am happy to add a multiple level of support for host readiness as I think that will be a
good enhancement to the feature as it stands today.

Subject: Re: Bypass software install on hosts

I'm wondering if I could maybe do something to the Ambari Agent code to
skip the actual install and setup process and make it think that finished
and report back to the server that it completed.

Any thoughts on this? A more elegant solution would be cool, just trying to
do a POC first.
