> Direct byte buffer used in #3638, which has memory leak
>
> DirectByteBuffer are cleaned in offheap memory by JVM, when GC happens (when
> heap is full). Consider a scenario, where heap is not full, but offheap is
> getting full. In this case DirectByteBuffers is not cleaned as GC not
> happened. This time we may get OOM from offheap memory and yarn may kill the
> jvm process. So, it is better to clean up the DirectByteBuffers after the
> usage by calling a reflection method.
