Hi!
I run 2 to spark an option
SPARK_MAJOR_VERSION=2 pyspark --master yarn --verbose
spark starts, I run the SC and get an error, the field in the table exactly there. not the problem

Your rdd is getting empty somewhere. The null pointer exception indicates that an aggregation task is attempted against of a null value. Check your data for null where not null should be present and especially on those columns that are subject of aggregation, like a reduce task, for example. In your case, it may be the id field.

possibly you are hitting this bug in spark codegen https://issues.apache.org/jira/browse/SPARK-18528
