- ||bsp.framework.name||yarn||In order to run Hama on YARN, it must be set this property.
This property means run applications on YARN.||
  ||hama.appmaster.memory.mb||100mb||The amount of memory used by the BSPApplicationMaster.
The total amount of memory used by the ApplicationMaster is calculated as follows. ''memoryInMb
= 3 * BSP_TASK_NUM + hama.appmaster.memory.mb''. This is because the application master spawns
1-3 thread per launched task that each should take 1mb, plus a minimum of base memory usage
of 100. If you face memory issues, you can set this to a higher value.||
