When run sparkR.session()

I faced below error:

Spark package found in SPARK_HOME: /databricks/spark
 
Launching java with spark-submit command /databricks/spark/bin/spark-submit sparkr-shell /tmp/Rtmp5hnW8G/backend_porte9141208532d
 
Error: Could not find or load main class org.apache.spark.launcher.Main
 
/databricks/spark/bin/spark-class: line 101: CMD: bad array subscript
 
Error in sparkR.sparkContext(master, appName, sparkHome, sparkConfigMap, :
 
JVM is not ready after 10 seconds

When I checked the cluster log4j , I found I hit the Rbackend limit:
