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. > Of course, the default value of this option should be true. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
