Subject [jira] [Updated] (HBASE-17017) Remove the current per-region latency histogram metrics
Date Fri, 04 Nov 2016 22:57:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-17017?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
