But for Long running service applications, this is not ideal. > The problems we have are: > 1) LRS applications are expected to run for a long time (weeks, months). > 2) Currently, all the container logs (from one NM) will be written into a > single file. The files could become larger and larger. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
