Automatic log expiration purges custom set replication log and metadata files too. These paths are set by Log Path and Directory for Metadata arguments that are present on the UI as per the schedule fields. It is the user's responsibility to set valid paths (For example, specify the legal HDFS paths that are writable by current user) and maintain this information for each replication policy.
