Subject [jira] [Updated] (HBASE-8420) Port HBASE-6874 Implement prefetching for scanners from 0.89-fb
Date Mon, 20 May 2013 22:07:16 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jimmy Xiang updated HBASE-8420:

    Status: Patch Available  (was: Open)

Attached v5.  In case a submitted task is interrupted by cancel(), the prefetched result size
counter is reduced if it is already increased.  Also added some change to make the test not
flaky by making sure the right region scanner holder is used to check prefetching flag/counter
in the test.
