Mukul Kumar Singh updated HDFS-12339:
-------------------------------------
Attachment: HDFS-12339.001.patch
Please find the attached patch which fixes this issue.
I have tested this my starting a nfs server using ambari. Without this patch I
was able to reproduce the issue.
Also after the patch, the nfs and mountd daemon are un-regisered.
{code}
[vagrant@c6803 ~]$ rpcinfo -p
program vers proto port service
100000 4 tcp 111 portmapper
100000 3 tcp 111 portmapper
100000 2 tcp 111 portmapper
100000 4 udp 111 portmapper
100000 3 udp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 48682 status
100024 1 tcp 60059 status
{code}
Following is the snippet of the nfs3 logs after the fix.
