Version Compatibility for maprdb-spark?

I'm following the instructions here Configuring the MapR-DB OJAI Connector for Apache Spark  in order to try to digest to MapR-DB from Spark.  I see that our cluster is running mapr-core-


The instructions specifically ask for maprdb-spark@5.2.1-mapr, and the repository does not have a 5.2.0 version of this particular artifact: Index of /groups/mapr-public/com/mapr/db/maprdb-spark.


Will they work okay together or am I going to have trouble later on due to this pairing? I realize it's just a minor version bump but I've had trouble with similar things in the past on different projects .


* Slight amendment* I just found this at the bottom:

To use the MapR-DB OJAI Connector for Apache Spark, you must have the following minimum software versions:

  • MapR release: 5.2.1 or later

Does that mean the whole cluster has to be upgraded to 5.2.1 from our 5.2.0?  or is it a client side thing?  I get confused .
