Description
In the thread 'Is it able to specify the percentage of memory instead of # of MB', Steve suggested:
We could do something where we can query YARN for the maximum amount an app can ask for (the AM finds this out when registered), and the capacity could be derived as a percentage of that.
Rather than percentage of available RAM, it's just a fraction of what you
are allowed.
This percentage can be expressed using 'x%' as the value for "yarn.memory" parameter of each component where x is between 1 and 100.
