Fabric Native Execution

Question

Hi ,

Is the native execution avaialble for free trails? I signed up for a free trial , but when i had attempted the Fabric Native Execuiton, The launch of Spark App failed as below

	at org.apache.spark.deploy.yarn.ApplicationMaster$$anon$2.run(ApplicationMaster.scala:757)
Caused by: java.lang.ClassNotFoundException: org.apache.spark.shuffle.sort.ColumnarShuffleManager

My Spark launc prop as below

%%configure 
{ 
   "conf": {
       "spark.native.enabled": "true", 
       "spark.shuffle.manager": "org.apache.spark.shuffle.sort.ColumnarShuffleManager" 
   } 
}

The way intepreted this, is the additional jars needed for this shuffle may not be in the classpath load. Which made me suspect if the Fabic Spark Pool i attemped is having the needed feature to support .

To test that , i had separately executed the property

"spark.native.enabled": "true", 

I could not notice any Changes to Spark Plan and it was as before. Anything am missing here?
