Description

We found TEZ progress stays at 0% (from ResourceManager WebUI or REST) for most of times.  While for some simple queries, it can be correctly updated.

After some debugging, it seems due to the fix of TEZ-3982 :
 

+      float dagProgress = progress / getTotalVertices();
+      if (dagProgress >= 0.0f && progress <= 1.0f) {
+        return dagProgress;
+      } else {
+        return 0.0f;

So the dagProgress will be only updated if progress is less than 1.0, but it's not true for most cases.
