hi @kapilsingh5050 can you also include #16244? It does fix the maven tests. |
|
Yes, I'll do that but the test failures here are different. I'm still to figure out the root cause. |
…with nested wide schema The wide schema, the expression of fields will be splitted into multiple functions, but the variable for loopVar can't be accessed in splitted functions, this PR change them as class member. Added regression test. Author: Davies Liu <davies@databricks.com> Closes apache#12338 from davies/nested_row. Conflicts: sql/core/src/test/scala/org/apache/spark/sql/execution/datasources/json/JsonSuite.scala
## What changes were proposed in this pull request? After apache#15620 , all of the Maven-based 2.0 Jenkins jobs time out consistently. As I pointed out in apache#15620 (comment) , it seems that the regression test is an overkill and may hit constants pool size limitation, which is a known issue and hasn't been fixed yet. Since apache#15620 only fix the code size limitation problem, we can simplify the test to avoid hitting constants pool size limitation. ## How was this patch tested? test only change Author: Wenchen Fan <wenchen@databricks.com> Closes apache#16244 from cloud-fan/minor.

What changes were proposed in this pull request?
Fix for SPARK-18091 which is a bug related to large if expressions causing generated SpecificUnsafeProjection code to exceed JVM code size limit.
This PR changes if expression's code generation to place its predicate, true value and false value expressions' generated code in separate methods in context so as to never generate too long combined code.
How was this patch tested?
Added a unit test and also tested manually with the application (having transformations similar to the unit test) which caused the issue to be identified in the first place.
