- Field Detail
  - DEFAULT_CPU_CAP
```
public static final int DEFAULT_CPU_CAP
```
    CPU resource amount is considered as number of cores. Each core can perform a single job.
  - DEFAULT_MEMORY_CAP
```
public static final int DEFAULT_MEMORY_CAP
```
    Memory resource unit size has been chosen arbitrarily. We can tune the value if we need.
  - DEFAULT_DISK_IO_CAP
```
public static final int DEFAULT_DISK_IO_CAP
```
    Disk IO resource unit size has been chosen arbitrarily. Since most of the jobs are light, we think disk can handle this amount of light jobs: reading/writing some small data.

    Constant Field Values
  - DEFAULT_NETWORK_IO_CAP
```
public static final int DEFAULT_NETWORK_IO_CAP
```
    Network IO resource unit size has been chosen arbitrarily. Since most of the jobs are light, we think network can handle this amount of light jobs: sending/receiving some small data.
