Release Note:The metric fsReadLatency records the number of sequential reads. The metric fsPreadLatency records the number of random reads.
HBase does sequential reads for compactions and positional random reads for satisfying user's queries. It would be nice if we can measure their latencies separately. It is mostly the random reads that dominate a transactional workload.
