When I cache a variable the data never shows up in the
storage tab. The storage tab is always blank. I have tried it in
Zeppelin as well as spark-shell.
scala> val classCount = spark.read.parquet("s3:// ..../classCount")
scala> classCount.persist
scala> classCount.count
Nothing shows up in the Storage tab of either Zeppelin or spark-shell.
However, I have several running applications in production that does
show the data in cache. I am using Scala and Spark 2.2.1 in EMR. Any
workarounds to see the data in cache.
The problem is mentioned here:
