--------------------------------------------
Summary: Change the default AM retry value to be not one
Key: YARN-542
URL: https://issues.apache.org/jira/browse/YARN-542
Project: Hadoop YARN
Issue Type: Bug
Reporter: Vinod Kumar Vavilapalli
Today, the AM max-retries is set to 1 which is a bad choice. AM max-retries
accounts for both AM level failures as well as container crashes due to
localization issue, lost nodes etc. To account for AM crashes due to problems
that are not caused by user code, mainly lost nodes, we want to give AMs some
retires.
I propose we change it to atleast two. Can change it to 4 to match other
retry-configs.
