>
> Key: AMBARI-25235
> URL: https://issues.apache.org/jira/browse/AMBARI-25235
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.6.2, 2.7.3
> Reporter: Papirkovskyy Myroslav
> Assignee: Papirkovskyy Myroslav
> Priority: Critical
> Labels: pull-request-available
> Fix For: 2.6.2, 2.8.0, 2.7.4
>
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> Background:
> On the cluster with 5-6 nodes conf-select cycles takes 3 seconds. Trying to
> create conf-dir for every single components. Which makes install stages like
> ~25-30seconds for hosts with a lot of clients.
> Usually we run conf-select during every task. Since with every single install
> new packages might appear and new conf-select links will be required.
> Solution:
> If host_sysprep is true, run conf-select cycle only during first task and
> than create a file indicating this was done, so other tasks skip.
> Since all packages are preinstalled this should work fine as during first
> single run it will be possible to create all links.
