--------------------------------------
Hi Vinay, I'm not sure I agree with the premise of this JIRA. The issue that
precipitated HDFS-2914 was that if the shared edits dir temporarily
disappeared, the Standby NN should not enter safemode. If the standby starts up
fresh and its disks are full, I see no reason it shouldn't go into safemode.
Thoughts?
> Standy NameNode is entering into Safemode even after HDFS-2914 due to
> resources low
