Using a custom MapR security configuration (optional)
If the default security configuration of your MapR cluster has been changed, you
need to configure the Job to be executed to take this custom security configuration
into account.
MapR specifies its security configuration in the mapr.login.conf file located in /opt/mapr/conf of the cluster. For further information about this
configuration file and the Java service it uses behind, see mapr.login.conf
and JAAS.
To configure your Job, you need to define the related
parameters in the Basic settings tab and the
Advanced settings tab of the Component view of the component you want your Job to use
to connect to MapR.
If you are using a MapReduce Job, you need to define the related parameters in the Hadoop configuration
tab of the Job.
If you are designing a Spark
Job, you need to do the related configuration in the Spark
configuration tab of the Job.
Proceed as follows to do the configuration:
-
Verify what has been changed about this mapr.login.conf
file.You should be able to obtain the related information from the administrator or the developer of your MapR cluster. -
If the location of the MapR configuration files has been changed to somewhere else in the
cluster, that is to say, the MapR Home directory has been changed, select
the Set the MapR Home directory check box
and enter the new Home directory. Otherwise, leave this check box clear and
the default Home directory is used. -
If the login module to be used in the mapr.login.conf file
has been changed, select the Specify the Hadoop
login configuration check box and enter the module to be called
from the mapr.login.conf file. Otherwise,
leave this check box clear and the default login module is used.For example, enter kerberos to call the hadoop_kerberos module or hybrid to call the hadoop_hybrid module.
