-----------------------------------
Summary: Cap the length of toCommentSafeString at 128 chars
Key: SPARK-14225
URL: https://issues.apache.org/jira/browse/SPARK-14225
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Reynold Xin
Assignee: Reynold Xin
I just saw a query with over 1000 fields and the generated expression comment
is pages long. At that level printing them no longer gives us much benefit. We
should just cap the length at some level.
