Data injestion from MaprFs

Hi all ,

I am new to druid and  tried to index data from our Mapr FS to druid to do some data analytics. But I  encounter a few problems:

In the index.json, I specified the paths: "maprfs:///app/xxxx/sample.json" and "hadoopDependencyCoordinates":["org.apache.hadoop:hadoop-client:2.7.0"],

I copied Mapr related jars from /opt/mapr/lib to druid hadoop-dependencies/hadoop-client/2.7.0/

The jvm parameters I specified : -Djava.library.path=/opt/mapr/lib -classpath /opt/mapr/conf:/opt/mapr/lib/maprfs-5.1.0- mapr.jar

when I curl to 8090, the task failed and I get this error:

   java.lang.RuntimeException: failure to login: No LoginModules configured for hadoop_default
 I was totally lost and did not find solution. Do you have any ideas about this?

 Thanks in advance!
