Subject [jira] [Updated] (TEZ-4320) DAGAppMaster progress not updated correctly
Date Fri, 16 Jul 2021 06:13:00 GMT

     [ https://issues.apache.org/jira/browse/TEZ-4320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Xiaomin Zhang updated TEZ-4320:
-------------------------------
    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 :
 
{noformat}
+      float dagProgress = progress / getTotalVertices();
+      if (dagProgress >= 0.0f && progress <= 1.0f) {
+        return dagProgress;
+      } else {
+        return 0.0f;
{noformat}

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