wenxin he commented on HADOOP-14508: ------------------------------------ hi [~shv], sorry to disturb you. Would you mind reviewing this patch? When I use TestDFSIO to benchmark hdfs, I found using -seq options can let TestDFSIO writing files to hdfs straightly without mr. But I got a NPE when using -seq. I found TestDFSIO#sequentialTest was broken when we refactoring TestDFSIO, so I try to fix this issue. Now, Hadoop QA passed. I also tested several use cases below. So, would you mind reviewing this?
