> 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
> Assignee: Apache Spark
> Priority: Major
>
> 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.}}
> {{}}
> {{}}
