I noticed this today.
The resource manager Node View shows that there is issue with DH07 log directories :
1/3 local-dirs are bad: /nfs/hadoop/yarn/local; 1/3 log-dirs are bad: /nfs/hadoop/yarn/log
A look at the disk partitions give the below. There seems to be plenty of space in there
[root@dh07 ~]# df -h

The Ambari Dashboard does not indicate any issues with DH07 and has the following
I am trying to understand if this is symptomatic of some other issue that i should be looking into.
