rdblue opened a new pull request #23608: [SPARK-26682][SQL] Use taskAttemptID instead of attemptNumber for Hadoop.
URL: https://github.com/apache/spark/pull/23608
 
 
   ## What changes were proposed in this pull request?
   
   Updates the attempt ID used by FileFormatWriter. Tasks in stage attempts use the same task attempt number and could conflict. Using Spark's task attempt ID guarantees that Hadoop TaskAttemptID instances are unique.
   
   ## How was this patch tested?
   
   Existing tests.
