> Accurately compute the test execute time in DFSIO

> Key: MAPREDUCE-6729
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6729
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: benchmarks, performance, test
> Affects Versions: 2.9.0
> Reporter: mingleizhang
> Assignee: mingleizhang
> Priority: Minor
> Labels: performance, test
> Attachments: MAPREDUCE-6729.001.patch, MAPREDUCE-6729.002.patch
>
>
> When doing DFSIO test as a distributed i/o benchmark tool. Then especially
> writes plenty of files to disk or read from, both can cause performance issue
> and imprecise value in a way. The question is that existing practices needs
> to delete files when before running a job and that will cause extra time
> consumption and furthermore cause performance issue, statistical time error
> and imprecise throughput while the files are lots of. So we need to replace
> or improve this hack to prevent this from happening in the future.
> {code}
> public static void testWrite() throws Exception {
> FileSystem fs = cluster.getFileSystem();
> long tStart = System.currentTimeMillis();
> bench.writeTest(fs); // this line of code will cause extra time
> consumption because of fs.delete(*,*) by the writeTest method
> long execTime = System.currentTimeMillis() - tStart;
> bench.analyzeResult(fs, TestType.TEST_TYPE_WRITE, execTime);
> }
> private void writeTest(FileSystem fs) throws IOException {
> Path writeDir = getWriteDir(config);
> fs.delete(getDataDir(config), true);
> fs.delete(writeDir, true);
> runIOTest(WriteMapper.class, writeDir);
> }
