在pyspark会话中，我想将文件从s3复制到hadoop集群本地目录，执行此操作时出现以下错误。请帮忙。

file_system.copyToLocal(false, java_path_src, java_path_dst)

参数-

java_path_src - s3://sandbox/metadata/2018-06-07T183915/test.jsonl
 java_path_dst - /home/hadoop/output/

错误-

py4j.protocol.Py4JError: An error occurred while calling o144.copyToLocal. Trace:
py4j.Py4JException: Method copyToLocal([class org.apache.hadoop.fs.Path, class org.apache.hadoop.fs.Path]) does not exist
