[jira] [Created] (SPARK-32996) Handle Option.empty v1.ExecutorSummary#peakMemoryMetrics

Shruti Gumma created SPARK-32996:
------------------------------------

             Summary: Handle Option.empty v1.ExecutorSummary#peakMemoryMetrics
                 Key: SPARK-32996
                 URL: https://issues.apache.org/jira/browse/SPARK-32996
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 3.1.0
            Reporter: Shruti Gumma


When {{peakMemoryMetrics}} in {{ExecutorSummary}} is {{Option.empty}}, then the {{ExecutorMetricsJsonSerializer#serialize}} method does not execute the {{jsonGenerator.writeObject}} method. This causes the json to be generated with {{peakMemoryMetrics}} key added to the serialized string, but no corresponding value.
This causes an error to be thrown when it is the next key {{attributes}} turn to be added to the json:
{{com.fasterxml.jackson.core.JsonGenerationException: Can not write a field name, expecting a value.}}

{{}}
