Yes, it should be enough. Please check this link <https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/admin_nn_memory_config.html> for sizing the namenode memory. 100 nodes is not too big by Hadoop standards so you shouldn't need too much there (unless you're storing millions of very small files). For the RM, generally 4GB is sufficient.
