> Just did an init on a new 1.6.1-SNAP cluster, and noticed the following permissions:
> {noformat}
> dfs -ls /
> Found 4 items
> drwxr-xr-x - accumulo supergroup 0 2014-05-14 09:48 /accumulo
> drwxr-xr-x - hdfs supergroup 0 2014-05-14 08:10 /jobtracker
> drwxrwxrwx - hdfs supergroup 0 2014-05-14 08:10 /tmp
> drwxr-xr-x - hdfs supergroup 0 2014-05-14 09:48 /user
> -bash-4.1$ hdfs dfs -ls /accumulo
> Found 3 items
> drwxr-xr-x - accumulo supergroup 0 2014-05-14 09:55 /accumulo/instance_id
> drwxr-xr-x - accumulo supergroup 0 2014-05-14 09:55 /accumulo/tables
> drwxr-xr-x - accumulo supergroup 0 2014-05-14 09:55 /accumulo/version
> {noformat}
> I previously set up /accumulo as 755, under the understanding that clients need access to /accumulo/instance_id
> things to fix
> # make init chmod tables and wals to 700, as a defensive measure to avoid data leaks
> # maybe also make sure if the trash is enabled that our user directory is also not world readable
> # If clients don't need access to instance_id, include a check that the data dir is not world readable
> Workaround: manually change permissions after init
