If not, users need to read code. {code} boolean smallMemory = ( (Math.max(conf.getLong(MRJobConfig.MAP_MEMORY_MB, 0), conf.getLong(MRJobConfig.REDUCE_MEMORY_MB, 0)) <= sysMemSizeForUberSlot) || (sysMemSizeForUberSlot == JobConf.DISABLED_MEMORY_LIMIT)); boolean smallCpu = Math.max( conf.getInt( MRJobConfig.MAP_CPU_VCORES, MRJobConfig.DEFAULT_MAP_CPU_VCORES), conf.getInt( MRJobConfig.REDUCE_CPU_VCORES, MRJobConfig.DEFAULT_REDUCE_CPU_VCORES)) <= sysCPUSizeForUberSlot {code} -- This message was sent by Atlassian JIRA (v6.2#6252)
