Is Scala 2.11 compitable with HDP2.3.4?

[#1]

Currently we are using HDP2.3.4 with Spark1.5.2 and Scala 2.10.

Can we upgrade Scala 2.11 without upgrading Spark and HDP?

Thanks for your help!

No. You will at the least need to build spark for 2.11. From spark apache documentation,

To produce a Spark package compiled with Scala 2.11, use the -Dscala-2.11 property:

./dev/change-scala-version.sh 2.11
mvn -Pyarn -Phadoop-2.4 -Dscala-2.11 -DskipTests clean package 

Spark does not yet support its JDBC component for Scala 2.11.
