Rewrap OutOfMemoryError in allocateUnpooledOffHeap with better message

    XMLWordPrintableJSON

    Details

      Description

      Now if Flink allocates direct memory in MemorySegmentFactory#allocateUnpooledOffHeapMemory and its limit is exceeded for any reason, e.g. user code over-allocated direct memory, ByteBuffer#allocateDirect will throw a generic "OutOfMemoryError: Direct buffer memory". We can catch it and add a message which provides more explanation and points to an option taskmanager.memory.task.off-heap.size to increase as a possible solution.
