I honestly haven't found it to be "much faster than MR", though it is usually a bit faster.</P><P>But I like MR because it integrates very well with the Application Manager GUI. I can find all my logs very easily through the GUI, and even share links with my team when there is a stack track or something in the logging that needs attention.</P><P>It also makes it very easy to diagnose when one node on our cluster is a bottleneck. When a query runs slowly, I can watch the mappers and reducers, and can easily see which servers are taking the longest.</P><P>I don't know of a good way to do any of those things with Tez. We use the Tez View, but it is buggy. And when it works, it takes many more clicks to find answers.</P><P>That's just my experience. Maybe there's a better way to leverage Tez...</P> Tue, 29 Mar 2016 20:30:14 GMT zack_riesland 2016-03-29T20:30:14Z
