> In the [YARN Services configuration document|https://hadoop.apache.org/docs/r3.2.0/hadoop-yarn/hadoop-yarn-site/yarn-service/Configurations.html], the description of {{yarn.service.am-resource.memory}} says,
> bq. Memory size in GB for the service AM (default 1024).
> which should be {{MB}} as this is used [here|https://github.com/apache/hadoop/blob/49ddd8a6ed5b40d12defb0771b4c8b53d4ffde3f/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-services/hadoop-yarn-services-core/src/main/java/org/apache/hadoop/yarn/service/client/ServiceClient.java#L1008] and {{Resource.newInstance}} creates {{LightWeightResource}}. The unit for memory is megabytes as described in [javadocs|https://github.com/apache/hadoop/blob/49ddd8a6ed5b40d12defb0771b4c8b53d4ffde3f/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/api/records/impl/LightWeightResource.java#L44]
