> spark.memory.offHeap.size accept 1G or 1KB also. So User is able to give
> suffix also but description say only *'absolute amount of memory in bytes'.*
> This require to update like *spark.driver.memory* where it is mentioned is
> accepts *a size unit suffix ("k", "m", "g" or "t") (e.g. {{512m}}, {{2g}}).*
>
> |{{spark.memory.offHeap.size}}|0|The *absolute amount of memory in bytes*
> which can be used for off-heap allocation. This setting has no impact on heap
> memory usage, so if your executors' total memory consumption must fit within
> some hard limit then be sure to shrink your JVM heap size accordingly. This
> must be set to a positive value when {{spark.memory.offHeap.enabled=true}}.|
