---------------------------------------
Hi vinod ,
By enabling yarn.resourcemanager.am.max-retries in yarn-site.xml the RM retries
specified number of times before failing the job. Thanks
> Resource manager is not respawning MRAppMaster process if it goes down in the
> middle of job execution and the job is getting failed.
