Cloudera documentation typo

Flume configuration for Kerberos as per documentation is:

<property>
<name>flume.kerberos.user</name>
<value>flume/host1.com@REALM.COM </value>
<description></description>
</property>

<property>
<name>flume.kerberos.keytab</name>
<value>/etc/flume/conf/keytab.krb5 </value>
<description></description>
</property>

But as per code the the configuration names are :

1. flume.security.kerberos.principal
2. flume.security.kerberos.keytab

In the installation documentation , they are mentioned as: flume.security.kerberos.user

<property>
<name>flume.security.kerberos.user</name>
<value>flume/_HOST@YOUR-REALM.COM</value>
<description></description>
</property>

This results in an error which is misleading:
