This can be a > problem for HDFS if you have a cluster with many nodes as you’ll slowly start > accumulating many (possibly small) files per YARN application. The current > “solution” for this problem is to configure YARN (actually the JHS) to > automatically delete these files after some amount of time. > 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)
