Yarn Log Aggregation Directory


Hi all,
I would like to know if it is possible to specify a location other than HDFS (eg. remote NFS Storage) for the parameter yarn_nodemanager_remote_app_log_dir because we don't have enough space on HDFS and we need to maintain the current policy retention (7 days).
Thanks in advance.

Yes you can use but the problem with that will be you have to allow all the users to access that directory. YARN can move local logs securely onto HDFS or a cloud-based storage, such as AWS. This allows the logs to be stored for a much longer time than they could be on a local disk, allows faster search for a particular log file and optionally can handle compression.
