I validated this in full dev. After full finishes building these are the
HDFS permissions:
```
[root@node1 vagrant]# hdfs dfs -ls /apps/metron/pcap
Found 3 items
drwxrwxr-x - metron hadoop 0 2018-08-15 18:34
/apps/metron/pcap/input
drwxrwxr-x - metron hadoop 0 2018-08-15 18:34
/apps/metron/pcap/interim
drwxrwxr-x - metron hadoop 0 2018-08-15 18:34
/apps/metron/pcap/output
```
After Kerberos is enabled and REST is restarted, the permissions are:
```
[root@node1 vagrant]# hdfs dfs -ls /apps/metron/pcap
Found 3 items
drwxr-xr-x - metron hadoop 0 2018-08-15 18:34
/apps/metron/pcap/input
drwxr-xr-x - metron hadoop 0 2018-08-15 18:34
/apps/metron/pcap/interim
drwxr-xr-x - metron hadoop 0 2018-08-15 18:34
/apps/metron/pcap/output
```
