> The presto S3 filesystem uses a staging directory on the local disk (for buffering data or something). This directory by default points to {{/tmp}}.
> We often see users configuring a special directory for temporary files via {{io.tmp.dirs}}, and it would make sense to automatically set the {{staging-directory}} to the same path, iff it was not explicitly configured.
> The corresponding property is {{presto.s3.staging-directory}}, found at {{com.facebook.presto.hive.s3.PrestoS3FileSystem.S3_STAGING_DIRECTORY}}.
