When you want use Hadoop-compatible file system as the spooling storage location,
you should enable `exchange.hdfs.skip-directory-scheme-validation` in `exchange-manager.properties`
when configure `exchange.base-directories` with a specific scheme instead of `hdfs` and the following steps

on all Trino cluster nodes.
