Re: How to validate that what was retrieved from Ignite cache is not NULL or empty?

Hi, Your expectation is correct. The second IgniteRDD will connect to the same Ignite cache that will already have all the data. This was you can share the data between applications. Zero in 'IgniteRDD[0]' string is just an ID within SparkContext, so it doesn't tell anything about the cached
