Summary: class
"org.apache.spark.sql.catalyst.expressions.GeneratedClass$SpecificUnsafeProjection"
grows beyond 64 KB
Key: SPARK-18207
URL: https://issues.apache.org/jira/browse/SPARK-18207
Project: Spark
Issue Type: Bug
Components: Optimizer, SQL
Affects Versions: 2.0.1, 2.1.0
Reporter: Don Drake
I have 2 wide dataframes that contain nested data structures, when I explode
one of the dataframes, it doesn't include records with an empty nested
structure (outer explode not supported). So, I create a similar dataframe with
null values and union them together. See SPARK-13721 for more details as to
why I have to do this.
I was hoping that SPARK-16845 was going to address my issue, but it does not.
I was asked by [~lwlin] to open this JIRA.
I will attach a code snippet that can be pasted into spark-shell that
duplicates my code and the exception. This worked just fine in Spark 1.6.x.
