@cloud-fan @kapilsingh5050 it's weird, but it looks like after this change,
all of the Maven-based 2.0 Jenkins jobs now time out. It looks consistent:
https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/
They all end like this:
```
CodeGenerationSuite:
- multithreaded eval
- metrics are recorded on compile
- SPARK-8443: split wide projections into blocks due to JVM code size limit
- SPARK-13242: case-when expression with large number of branches (or cases)
