It might be better to switch it off once for all by editing /etc/selinux/config Olivier On 10 Jun 2014 08:21, "Meghavi Sugandhi" <meghavi.sugan...@tcs.com> wrote: Hi After running the below command, echo 0 >/selinux/enforce I am still getting same error in /var/log/messages.

All rrd files related to Namenode, HBase, Mapreduceare are being written to /var/lib/ganglia/rrds/ I cant disable SELinux. Because disabling it requires rebooting of system.
