             Summary: Add stderr output of Ambari auto-recovery commands in agent log
                 Key: AMBARI-15393
                 URL: https://issues.apache.org/jira/browse/AMBARI-15393
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent
    Affects Versions: 2.2.1
            Reporter: Sandor Magyari
            Assignee: Sandor Magyari
            Priority: Critical
             Fix For: 2.2.2


Customers rely on Ambari auto-recovery logic to recover from component start failures during cluster create. The idea is to improve reliability (through retries) by sacrificing some of the latency.
In some cases we see that cluster creates fail because component start fails and auto-recovery is unable to start those components for up to 2 hrs, most often on headnodes for HIVE_SERVER, OOZIE_SERVER, and NAMENODE components.
The problem these kind of problems are hard to investigate later, as auto recovery files are not sent to server side nor they are saved in ambari agent logs, only stored on agent . 
The solution is to add a new an option log_auto_execute_errors in logging section to ambari-agent.ini. In case this is enabled agent will append stderr of auto recovery command to agent log.
