Ajith S commented on HDFS-8940:
-------------------------------

Hi all,

Design document suggests polling from SbNN(without inotify). I think as [~cmccabe] and [~surendrasingh]
mentioned "read-inotify-from-standby" also seems to be good approach, but we may also have
to consider "delayed namespace information" in SbNN

 [~mingma] thanks for the design

> HDFS-6634 provides the core inotify functionality. We would like to extend that to provide
a large-scale service that ten of thousands of clients can subscribe to.
