I don't even think we can ask yarn for the percentage of memory I do understand what you are trying to do: ask for >51%.
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. On 2 December 2014 at 01:49, Sumit Mohanty <smoha...@hortonworks.com> wrote: > That is not possible.
