Sandor Magyari updated AMBARI-15393:
------------------------------------
Description:
Users 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_command_executes* in logging
section to *ambari-agent.ini*. In case this is enabled agent will append stderr
of all commands (including auto_execute commands) to agent log.
