>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager
>    Affects Versions: 2.7.1
>            Reporter: Chackaravarthy
>         Attachments: YARN-5445-1.patch
> Log aggregation is enabled and configured to write applogs to different cluster or different
namespace (NN federation). In these cases, would like to have some configs on attempts or
retries to fail fast in case the other cluster is completely down.
> Currently it takes default {{dfs.client.failover.max.attempts}} as 15 and hence adding
a latency of 2 to 2.5 mins in each container launch (per node manager).
