如何绕过此问题（无需重新编制索引）：

Py4JJavaError: An error occurred while calling o2649.load.
: org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: Incompatible types found in multi-mapping: Field [metadata.cscope.0] has conflicting types of [LONG] and [OBJECT].

我尝试通过es.read.field.exclude排除此字段，但没有帮助。
我的阅读：

reader = spark.read.format("org.elasticsearch.spark.sql") \
    .option("es.port", "9200") \
    .option("spark.es.net.http.auth.user", "") \
    .option("spark.es.net.http.auth.pass", "") \
    .option("es.nodes.wan.only", "true") \
    .option("es.mapping.date.rich", "false") \
    .option("es.http.timeout", "3m") \
    .option("es.read.field.include", "log") \
    .option("es.read.field.exclude", "metadata*") \
    .option("es.read.metadata", "false") \
    .option("es.nodes", IP)
df = reader.load(INDEX_NAME)
