Cheng Lian updated SPARK-11376:
-------------------------------
Description:
There are two {{mutableRow}} fields in the generated code within
{{GenerateColumnAccessor.create()}} method. However, Janino happily accepted
this code and accidentally operates normally.
After some experiments, it turned out that Janino doesn't complain as long as
all the fields with the same name are null.
was:
There are two {{mutableRow}} fields in the generated code within
{{GenerateColumnAccessor.create()}} method. However, Janino happily accepted
this code and operates normally. (That's why this bug is marked as minor.)
After some experiments, it turned out that Janino doesn't complain as long as
all the fields with the same name are null.
