I have been encountering multiple installation failures related to failed attempts to chmod or chown files in the /boot/efi file system.
I’m a little confused here: I’ve read that the efi file system is always FAT, which I didn’t think was POSIX-compliant, meaning I didn’t think you could do things like chmod or chown on files in a FAT file system.
This is how /boot/efi is mounted on my system:
[root@compute000 ~]# ssh compute005 ‘grep “/boot/efi” /etc/mtab’
/dev/sda1 /boot/efi vfat rw,uid=0,gid=0,umask=0077,shortname=winnt 0 0
[root@compute000 ~]# ssh compute005 ‘fdisk -l /dev/sda’

Take Falcon for example. The output from the Falcon install shows:
2015-03-05 11:03:30,463 – Changing permission for /boot/efi/hadoop/falcon/data/lineage/graphdb from 700 to 775
2015-03-05 11:03:30,463 – Changing owner for /boot/efi/hadoop/falcon/data/lineage/graphdb from 0 to falcon
But those commands won’t work on this /boot/efi file system:
[root@compute000 ~]# ssh compute005 ‘ls -la /boot/efi/hadoop/falcon’
total 6
drwx—— 3 root root 2048 Mar 5 10:56 .
drwx—— 3 root root 2048 Mar 5 10:56 ..
drwx—— 3 root root 2048 Mar 5 10:56 data
[root@compute000 ~]# ssh compute005 ‘chmod 775 /boot/efi/hadoop/falcon’
[root@compute000 ~]# ssh compute005 ‘ls -la /boot/efi/hadoop/falcon’
total 6
drwx—— 3 root root 2048 Mar 5 10:56 .
drwx—— 3 root root 2048 Mar 5 10:56 ..
drwx—— 3 root root 2048 Mar 5 10:56 data
[root@compute000 ~]# ssh compute005 ‘chown falcon /boot/efi/hadoop/falcon’
chown: changing ownership of `/boot/efi/hadoop/falcon': Operation not permitted
I guess there are 2 possible solutions for this, right?
1) HDP needs to use a different file system because it can’t work with /boot/efi on my cluster the way it expects to.
2) I need to install my nodes differently in a way that permissions in the /boot/efi file system can be modified with commands like chmod and chown.
I’m not sure which is more work for me, but I’m open to suggestions for either approach.
Or an option #3 if anyone has one…
Thanks,
Nate
