Compatibility with Mapr Client 5.2.1 and Mapr Cluster 5.2.2.

 

I have a Spark application that runs on a Mapr 5.2.1 client. If the Cluster is on version 5.2.2 and client on 5.2.1 or vica versa, the Spark Application is always killed with

 

18/02/12 08:10:00 INFO yarn.ApplicationMaster: Preparing Local resources
Exception in thread "main" java.io.IOException: No FileSystem for scheme: maprfs
        at org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2584)

 

If the client is on 5.2.2 and cluster on 5.2.2 there are no issues. Are there any workarounds to get, say a 5.2.2 client, to work with an existing 5.2.1 Cluster

 

Thanks

 

Mike
