    Description

      HBASE-8329 recently introduced on all branches double RegionServerServices#getCompactionPressure(), which returns a value greater than or equal to 0.0, and any value greater than 1.0 means we have exceeded the store file limit on some stores. It could be reasonable to send this value along in server load statistics (clamping max at 1.0), and consider it as an additional term in the ExponentialClientBackoffPolicy.
