Github user kiszk commented on the pull request: https://github.com/apache/spark/pull/10488#issuecomment-167424111 @hvanhovell, a set of following two conditions causes this compilation failure: 1. Use more than one string concatenations 2. Use scala 2.11 compiler (open question is that [this failure](https://amplab.cs.berkeley.edu/jenkins/view/Spark-Packaging/job/Spark-Master-Maven-Snapshots/1293/consoleFull) occurs by using both scala 2.10 and 2.11 compilers on Jenkins I can reproduce this compilation error by using the following command: ```` $ java -version openjdk version "1.8.0_65" OpenJDK Runtime Environment (build 1.8.0_65-b17) OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode) $ build/mvn -Dscala-2.11 -Pyarn -Phadoop-2.4 -DskipTests clean package install -pl sql/catalyst ````
