Viraj Jasani commented on HDFS-16219:
-------------------------------------
[~aajisaka] I just realized that even after HDFS-16217 is in, if we provide
router rename option as DISTCP, we still face this issue.
I think we might still want to fix this by providing default values of
rename.map and rename.bandwidth in hdfs-rbf-default, as 20 and 100
respectively. Thought?
