> Key: AMBARI-4324
> URL: https://issues.apache.org/jira/browse/AMBARI-4324
> Project: Ambari
> Issue Type: Improvement
> Components: ambari-agent, ambari-server
> Affects Versions: 1.5.0
> Reporter: Dmitry Lysnichenko
> Assignee: Dmitry Lysnichenko
> Fix For: 2.0.0
>
>
> As of now, task timeout at server and timeout at agent are two different
> mechanisms, that currently work independently and duplicate each other.
> Such behaviour leads to strange scenario:
> - cluster installation is started
> - execution of some command exceeds timeout
> - server considers this command and *all next* commands in request timed out.
> This state is shown at UI as well.
> - at the same time, agent considers currently executed command timed out an
> kills it. After that, agent starts executing the next command in queue. If
> next commands does not fail, agent sends COMPLETE status reports.
> - server receives COMPLETE status reports and updates component status.
> - if user clicks "Retry installation", only tasks for not installed
> components are created.
> - as a result, UI shows less tasks than user expects
> h1. Will be fixed by AMBARI-4323
