Error: Error in rxCall("RxSummary", params) :
This error is generally caused by a mismatched version of or missing scaleR-hadoop-0.1-SNAPSHOT.jar and should normally be found in /usr/lib/hadoop/lib/ as a result of a properly installing Revolution R Enterprise in a Hadoop cluster. Confirm that all instances of scaleR-hadoop-0.1-SNAPSHOT.jar in the cluster are the version matching the release of Revolution R Enterprise and are not left over from installations of older releases. Also confirm they are in the proper locations to be found in the library path in the Hadoop/RRE environment. Refer to the Revolution R Hadoop Configuration Guide for more information.
