Reynold Xin created SPARK-9448:
----------------------------------
Summary: GenerateUnsafeProjection should not share expressions
across instances
Key: SPARK-9448
URL: https://issues.apache.org/jira/browse/SPARK-9448
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Reynold Xin
Assignee: Reynold Xin
Priority: Blocker
We accidentally moved the list of expressions from the generated code instance
to the class wrapper, and as a result, different threads are sharing the same
set of expressions, which cause problems when the expressions have mutable
state.
