Hari Mankude commented on HDFS-2914:
------------------------------------
Uploaded patch. In the patch, I increased the default value of
RESOURCE_CHECK_INTERVAL from 5secs to 60secs. 5secs seems to be excessive for
this thread to run. If there are issues, I can remove the fix or modify the fix
if there is a better number.

> When shared edits dir is bounced, standby NN is put into safemode by the

> safe mode when shared edits dir reappears.
