Yiqun Lin commented on HDFS-13469:
----------------------------------
{quote}I'm not sure how to figure which subcluster has that inode.
{quote}
[~elgoiri], currently in the Router, I think we cannot directly know which
subcluster has the inode. The one way, we may try to get its HdfsFileStatus
from subclusters with the given source path, and verify the fileId in
HdfsFileStatus and confirm the desired subcluster(namespace). Not sure this is
the expected way as [~daryn] wants.
