# Using Amazon EMR container defaults classification
<a name="emr-eks-job-submitter-container-defaults"></a>

## Overview
<a name="emr-eks-job-submitter-container-defaults-overview"></a>

The following settings are available under the `emr-containers-defaults` classification:

** `job-start-timeout` **  
By default, a job will time out if it cannot start and it waits in the ` SUBMITTED` state for 15 minutes. This configuration changes the number of seconds to wait before the job times out.

** `executor.logging` **  
Enables or disables logging on the executor pods. When this is set to ` DISABLED` the logging container is removed from the executor pods, which will disable any logging for these pods specified in the `monitoringConfiguration`, such as `s3MonitoringConfiguration` or `cloudWatchMonitoringConfiguration`. When this setting is not set or is set to any other value, logging on the executor pods is enabled.

** `logging.image` **  
Sets a custom image to be used for the logging container on the driver and executor pods.

** `logging.request.cores` **  
Sets a custom value for the number of CPUs, in CPU units, for the logging container on the driver and executor pods. By default, this is not set.

** `logging.request.memory` **  
Sets a custom value for the amount of memory, in bytes, for the logging container on the driver and executor pods. By default, this is set to **512Mi**. A mebibyte is a unit of measure that's similar to a megabyte.
