             Summary: Add configuration to skip validating HFile format when bulk loading millions of HFiles
                 Key: HBASE-13985
                 URL: https://issues.apache.org/jira/browse/HBASE-13985
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.98.13
            Reporter: Victor Xu
            Assignee: Victor Xu
            Priority: Minor
             Fix For: 0.98.14


When bulk loading millions of HFile into one HTable, checking HFile format is the most time-consuming phase. Maybe we could use a parallel mechanism to increase the speed, but when it comes to millions of HFiles, it may still cost dozens of minutes. So I think it's necessary to add an option for advanced user to bulkload without checking HFile format at all.
