[jira] [HBASE-5072] Support Max Value for Per-Store Metrics
Summary:
We were bit in our multi-tenant cluster because one of our Stores
encountered a bug and grew its StoreFile count. We didn't notice this because
the StoreFile count currently reported by the RegionServer is an average of all
Stores in the region. For the per-Store metrics, we should also record the max
so we can notice outliers.
Test Plan: - mvn test -Dtest=TestRegionServerMetrics
