Time taken for Hadoop job to execute

Question

是否有一个API来确定Hadoop作业执行的时间（确切地说 - >没有黑客攻击。）？

Answer 1

I think the simplest way is to measure time in Your driver class. Is it ok for you? I mean something like this:

   long start = new Date().getTime();
   boolean status = job.waitForCompletion(true);            
   long end = new Date().getTime();
   System.out.println("Job took "+(end-start) + "milliseconds");
