Hi there, I am in the process of documenting the process required to integrate NiFi and MapR and I would like to confirm if the following process works for you folks as well:
*Is there any way to connect to a MapR cluster using the HDFS compatible API?* - A: Yes but it requires compiling NiFI from source. The process is rather straight forward: *If the cluster is running in secure mode (Kerberos)* 1. install mapr-client 2. configure mapr-client as per MapR documentation 3. After configuring the secure client, confirm everything is working by using `maprlogin kerberos` or `maprlogin password` followed by `hadoop fs -ls -d` 4. compile NiFi using the adequate profile: mvn -T2.0C -DskipTests=true -Pmapr -Dhadoop.version=<mapr_ artifact_version_as_per_mapr_documentation> where artifact version matches your MapR release. 5. Deploy nifi as per documentation, 6. modify bootstrap.conf so that it contains *java.arg.15=-Djava.security.auth.login.config=/opt/mapr/conf/mapr.login.conf * 7. create a core-site.xml with the following content: *<configuration>* * <property> <name>hadoop.security</name> <value>hybrid</value> </property> <property>* * <name>fs.defaultFS</name>* * <value>maprfs:///</value>* * </property>* *</configuration> * 8. the PutHDFS processor and point to the core-site.xml above, creating a kerberos keytab as customary 9. test
