Enis Soztutar updated HBASE-17017:
----------------------------------
Hadoop Flags: Incompatible change
Release Note: Removes per-region level (get size, get time, scan size and
scan time histogram) metrics that was exposed before. Per-region histogram
metrics with 1000+ regions causes millions of objects to be allocated on heap.
The patch introduces getCount and scanCount as counters rather than histograms.
Other per-region level metrics are kept as they are.
> Remove the current per-region latency histogram metrics
