   I used `LaunchDataIngestionJobCommand` with job config like this:
   
   ```
   executionFrameworkSpec:
            |  name: spark
            |  segmentMetadataPushJobRunnerClassName: org.apache.pinot.plugin.ingestion.batch.spark.SparkSegmentMetadataPushJobRunner
            |  segmentGenerationJobRunnerClassName: org.apache.pinot.plugin.ingestion.batch.spark.SparkSegmentGenerationJobRunner
            |  segmentUriPushJobRunnerClassName: org.apache.pinot.plugin.ingestion.batch.spark.SparkSegmentUriPushJobRunner
            |jobType: 'SegmentCreationAndMetadataPush'
            |inputDirURI: '$inputS3Prefix'
            |outputDirURI: '$outputS3Prefix'
            |includeFileNamePattern: 'glob:**/*.parquet'
            |overwriteOutput: true
            |pinotFSSpecs:
            |- scheme: s3
            |  className: org.apache.pinot.plugin.filesystem.S3PinotFS
            |  configs:
            |    region: $s3Region
            |recordReaderSpec:
            |  dataFormat: 'parquet'
            |  className: 'org.apache.pinot.plugin.inputformat.parquet.ParquetRecordReader'
            |tableSpec:
            |  tableName: $tableName
            |pinotClusterSpecs:
            |- controllerURI: $clusterString
            |segmentNameGeneratorSpec:
            |  type: normalizedDate
            |segmentCreationJobParallelism: 1000
            |pushJobSpec:
            |  segmentUriPrefix: 's3://$s3Bucket'
            |  segmentUriSuffix: ''
            |  pushParallelism: 5
            |  pushAttempts: 5
            |  pushRetryIntervalMillis: 3000
   ```
   
   I assume it reads table config from cluster when producing segment data. And no change was made to table config before / after.
   
   I can try to grab some stack trace / flamegraph.
