Change subject: IMPALA-8375: Add metrics for spill disk usage ...................................................................... IMPALA-8375: Add metrics for spill disk usage Added a new metric tmp-file-mgr.scratch-space-bytes-used-high-water-mark for tracking HWM for spilled bytes. A new class AtomicHighWaterMarkMetric was added to keep track of the current value and the HWM value. The current value for spilled bytes is incremented every time a new range is allocated from a temporary file. The current value for spilled bytes is decremented when a temporary file is closed. The new metric is not updated when ranges are recycled from a file. We can add a new metric in future for keeping track of actual spilled bytes. The HWM value is updated whenever the current value is greater than the HWM value.
