+ max_file_size: the size limit of a single file, if the result exceeds
this value, it will be cut into multiple files, the value range of
max_file_size is [5MB, 2GB] and the default is 1GB. (When specified that the
file format is ORC, the size of the actual division file will be a multiples of
64MB, such as: specify max_file_size = 5MB, and actually use 64MB as the
division; specify max_file_size = 65MB, and will actually use 128MB as cut
division points.)
delete_existing_files: default `false`. If it is specified as true,
you will first delete all files specified in the directory specified by the
file_path, and then export the data to the directory.For example: "file_path" =
"/user/tmp", then delete all files and directory under "/user/"; "file_path" =
"/user/tmp/", then delete all files and directory under "/user/tmp/"

+ max_file_size: 单个文件大小限制，如果结果超过这个值，将切割成多个文件, max_file_size取值范围是[5MB,
2GB], 默认为1GB。（当指定导出为orc文件格式时，实际切分文件的大小将是64MB的倍数，如：指定max_file_size = 5MB,
实际将以64MB为切分；指定max_file_size = 65MB, 实际将以128MB为切分）
delete_existing_files:
默认为false，若指定为true,则会先删除file_path指定的目录下的所有文件，然后导出数据到该目录下。例如："file_path" =
"/user/tmp", 则会删除"/user/"下所有文件及目录；"file_path" = "/user/tmp/",
则会删除"/user/tmp/"下所有文件及目录
