Suzanne McIntosh created KUDU-1662:
--------------------------------------
Summary: Kudu fs command reports permission denied
Key: KUDU-1662
URL: https://issues.apache.org/jira/browse/KUDU-1662
Project: Kudu
Issue Type: Bug
Affects Versions: 1.0.0
Environment: 1. Kudu demo Quickstart VM (VirtualBox) running CDH 5.8
2. New Kudu (VMWare) VM running CDH 5.8 in Centos 6.6. with Kudu installed from
command line (no CM)
Reporter: Suzanne McIntosh
Priority: Minor
This is a minor issue because the uuid is ultimately displayed.
Issuing 'kudu fs dump uuid ...' gives a permission denied error as shown below.
Testing against the Kudu demo VM yielded the same result. Using sudo gives a
different error.
My session below shows results of using plain kudu command, followed by an
attempt to clear the permission denied message by using sudo:
[training@localhost ~]$ kudu fs dump uuid -fs_wal_dir /var/lib/kudu/master
-fs_data_dirs /var/lib/kudu/master
