   > I think this is pretty similar to 
https://issues.apache.org/jira/browse/HDFS-14378. If I remember correctly, the 
better approach would be to have ANN roll its own edit logs.
   > 
   > Even though we address the observer issue here, in a real scenario there 
could still be multiple SNNs.
   
   Thank you @sunchao very much for your review.
   
   Active Namenode does automatically roll logs periodically. It might be risky 
(but I think it's ok) by simply disabling all SNN to trigger active roll edits 
log. However, disabling OBN rolle active edits has no side effects.

> To avoid frequent edtis rolling, we should disable OBN from triggering the

> It is sufficient to retain only the triggering of SNN and the auto rolling of
