Hello,
I have a weird issue, this request works fine:
sqlContext.sql("SELECT customer_id FROM transactions WHERE purchaseamount >=
200").count()
However, when I cache the table before making the request:
sqlContext.cacheTable("transactions")
sqlContext.sql("SELECT customer_id FROM transactions WHERE purchaseamount >=
200").count()
I am getting an exception on of the task:
: org.apache.spark.SparkException: Job aborted due to stage failure: Task
120 in stage 104.0 failed 4 times, most recent failure: Lost task 120.3 in
stage 104.0 (TID 20537, spark-w-0.c.internal): java.lang.ClassCastException:
(I have no details after the ':')
Any ideas of what could be wrong?
