Review comment:
I have this line of code to only set offHeapMemory when
`spark.memory.offHeap.enabled` is `true`:
```
if (conf.get(MEMORY_OFFHEAP_ENABLED)) {
// Explicitly add suffix b as default unit of offHeapMemory is Mib
ereqs.offHeapMemory(conf.get(MEMORY_OFFHEAP_SIZE).toString + "b")
}
```
Is this enough? if its disabled, the method won't be called, the default
value should be 0.
