Case 3: Secure MapR Cluster and Insecure HDFS Cluster

Describes how to configure access between a secure MapR cluster and an insecure HDFS cluster.

If a secure MapR cluster is accessing an insecure HDFS cluster with the hdfs:// protocol, modify the /opt/mapr/conf/ file on each node to replace ${MAPR_LOGIN_OPTS} with “-Dhadoop.login=maprsasl_permissive” in the HADOOP_JOBTRACKER_OPTS and HADOOP_TASKTRACKER_OPTS variables.

Launch any commands that need to access the HDFS cluster with the HADOOP_OPTS=-Dhadoop.login=hybrid Java property.
