It happens in Scala when using immutable data structures since that for each transformation the JVM will have to re-create a lot of new objects and remove the previous ones from the heap.The first approach works fine, the second ends up in another java.lang.OutOfMemoryError, this time about the heap. So, question: is there any programmatic alternative to this, for the particular use case (i.e., several small HashMap objects)? Two comments: xlConnect has the same problem. And more importantly, telling somebody to use a different library isn't a solution to the problem with the one being referenced. The default behavior for Apache Hive joins is to load the entire contents of a table into memory so that a join can be performed without having to perform a Map/Reduce step.

Each node has 8 cores and 2GB memory. I notice the heap size on the executors is set to 512MB with total set to 2GB. Since you are running Spark in local mode, setting spark.executor.memory won't have any effect, as you have noticed. The reason for this is that the Worker "lives" within the driver JVM process that you start when you start spark-shell and the default memory used for that is 512M. Create a temporary dataframe by limiting number of rows after you read the json and create table view on this smaller dataframe. E.g. if you want to read only 1000 rows, do something like this: small_df = entire_df.limit (1000) and then create view on top of small_df. You can increase the cluster resources.
