我正在尝试更新内部的配置单元连接器属性 /etc/presto/conf/catalog/hive.properties . 我补充说：
hive.s3.max-client-retries=50
hive.s3.max-error-retries=50
hive.s3.max-connections=500
hive.s3.connect-timeout=5m
hive.s3.socket-timeout=5m但由于某些原因，这些都不被接受。presto服务器重新启动失败，错误如下：

正如piotr提到的，emr从emr-5.12.0开始将默认的文件系统实现从prestos3filesystem更改为emrfs。prestos3filesystem属性将不可用，但您可以像配置任何其他应用程序一样配置emrfs。请参阅上的“emrfs and prestos3filesystem configuration”https://docs.aws.amazon.com/emr/latest/releaseguide/emr-presto-considerations.html 更多信息。

这些属性适用于
hive.s3-file-system-type设置为PRESTO. 当它是例如。EMRFS，这些配置属性不适用，设置它们会导致您观察到的错误。
