Data of type java.util.GregorianCalendar cannot be used

[SailLiao]

i use pyspark read a parquet file from hdfs and i hive a column type is timstamp , when i write the DataFrame to es , there is an exception Data of type java.util.GregorianCalendar cannot be used but when i not use the timestamp column , it works fine.

spark = SparkSession.builder.appName(" python es ") .config("spark.master", "yarn") .getOrCreate()
path = "/data/file/test.parquet"
df = spark.read.load(path, format='parquet')
esClient = ESClient(index=db_name, type=table_name, id_field=id_filed)
esClient.writeDF2ES(df)

es_conf={
      'es.mapping.id': 'xxxxx'
      'es.nodes': 'xxxxx'
      'es.resource': 'xxxxx'
}

def writeRDD2ES(rdd):
    try:
        rdd.saveAsNewAPIHadoopFile(
            path='-',
            outputFormatClass="org.elasticsearch.hadoop.mr.EsOutputFormat",
            keyClass="org.apache.hadoop.io.NullWritable",
            valueClass="org.elasticsearch.hadoop.mr.LinkedMapWritable",
            conf=es_conf)
    except:
        self.logger.error("Failed to write es(%s)" % self)
        raise
