Yang Wang commented on FLINK-17676:
-----------------------------------
I am afraid you could not roll the {{.out}} file currently since we do not use
a log4j to write the stdout file. Maybe we do not have some reasonable ways to
achieve this unless introducing the stdout/stderr stream redirection. When i
work on FLINK-17166, we already have some discussion there.
