Subject [jira] [Created] (TEZ-4320) DAGAppMaster progress not updated correctly
Date Fri, 16 Jul 2021 06:12:00 GMT
Xiaomin Zhang created TEZ-4320:

             Summary: DAGAppMaster progress not updated correctly
                 Key: TEZ-4320
                 URL: https://issues.apache.org/jira/browse/TEZ-4320
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Xiaomin Zhang

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;{noformat}
