C= urrently, there is a separate log file for each Node Manager. This can be = a problem for HDFS if you have a cluster with many nodes as you=E2=80=99ll = slowly start accumulating many (possibly small) files per YARN application.= The current =E2=80=9Csolution=E2=80=9D for this problem is to configure Y= ARN (actually the JHS) to automatically delete these files after some amoun= t of time. =20 We should improve this by compacting the per-node aggregated log files into= one log file per application. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
