Description

When we use the yarn-session.sh -q command, the basic information of the NM will be printed, and the memory unit is MB. If we have 128GB of memory, it will display 131072 MB. At the same time, if we have multiple NMs, finally totalMemeory doesn't show units.

This jira will use hadoop's StringUtil to format unit output.
