[jira] [Updated] (SPARK-32898) totalExecutorRunTimeMs is too big
[ https://issues.apache.org/jira/browse/SPARK-32898?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
wuyi updated SPARK-32898:
-------------------------
Description:
This might be because of incorrectly calculating executorRunTimeMs in Executor.scala
The function collectAccumulatorsAndResetStatusOnFailure(taskStartTimeNs) can be called when taskStartTimeNs is not set yet (it is 0).
As of now in master branch, here is the problematic code:
[https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/executor/Executor.scala#L470]
There is a throw exception before this line. The catch branch still updates the metric.
However the query shows as SUCCESSful. Maybe this task is speculative. Not sure.
submissionTime in LiveExecutionData may also have similar problem.
[https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/ui/SQLAppStatusListener.scala#L449]
