Xiaoqiao He commented on HDFS-15169:
------------------------------------
Thanks [~ayushtkn] for your helpful review comments.
{quote}Presently in the output, The path name is coming as of destination:

Exactly it is unexpected, this output is print by NameNode, and we have
resolved it at Router. Do we need to replace it at Router when receive result
from NN? I am not sure if it is graceful. After rough scan, it seems that DFCK
without RBF have the same issue? Any suggestions?
The original thought of redirect request to all active downstream NN is for the
inner path of mount point. It seems not very accurate, especially for FNF path.
About failover, is it proper to fix by retry?
Other comments are good catches. Will fix it later. Thanks again.

> HDFS-13989 implemented FSCK to DFSRouter, however, it just redirects the
> requests to all the active downstream NameNodes for now. The DFSRouter should
> consider the mount table when redirecting the requests.
