Wenchen Fan created SPARK-18909:
-----------------------------------
Summary: The error message in `ExpressionEncoder.toRow` and
`fromRow` is too verbose
Key: SPARK-18909
URL: https://issues.apache.org/jira/browse/SPARK-18909
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Wenchen Fan
Priority: Minor
In `ExpressionEncoder.toRow` and `fromRow`, we will catch the exception and put
the treeString of serializer/deserializer expressions in the error message.
However, encoder can be very complex and the serializer/deserializer
expressions can be very large trees and blow up the log files(e.g. generate
over 500mb logs for this single error message.)
We should simplify it.
