Subject Re: [Spark 2.0] Why MutableInt cannot be cast to MutableLong?
Date Mon, 01 Aug 2016 03:52:07 GMT
If I have a column store in a parquet file under INT type and I create a table with the same
column but change the time from int to bigint.

in Spark 2.0 it shows error:

Error: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage
259.0 failed 4 times, most recent failure: Lost task 0.3 in stage 259.0 (TID 22958, slave2):

So I think this error still happen in Spark 2.0
