Description
If a user utilizes the FUSE mount, then has a group change, they will be unable to write into FUSE using the new group information.
To duplicate (assuming user brian starts only in group brian):
1) Write file into FUSE (or do any other action)
2) Add user brian to group brian2
3) chown anything brian owns to brian:brian2. The error message that gets passed along is:
[brian@red ~]$ chown brian:brian2 /mnt/hadoop/user/brian/test_group_perms2
chown: changing ownership of `/mnt/hadoop/user/brian/test_group_perms2': Input/output error
I believe this is due to the fact that group information is only looked up at NN connection time?
If you then remount the FUSE mount, the chown command succeeds.
