Create a Kerberos Principal and a keytab File for Flume
Skip this task if you are not using Flume.
On each node where Flume is installed, use the following commands in a Linux-based Kerberos
environment to set up the identity and update the keytab
file:
# kadmin
: addprinc -randkey username/<FQDN@REALM>
: ktadd -k /opt/mapr/conf/flume.keytab username/<FQDN@REALM>
The flume.keytab
file must be owned and readable only by the mapr user.
