>    Affects Versions: 3.0.0
>            Reporter: Gengliang Wang

> When I try to run scripts (e.g. `./sbin/start-history-server.sh -h` in latest master,
I got such error:
> ```
> Presence of build for multiple Scala versions detected.
> Either clean one of them or, export SPARK_SCALA_VERSION in spark-env.sh.
> ```
> The error message is quite confusing and there is no `spark-env.sh` in our code base.

> As now with https://github.com/apache/spark/pull/22967, we can revise the error message
as following:
> ```
> Presence of build for both scala versions(SCALA 2.11 and SCALA 2.12) detected.
> Either clean one of them or, export SPARK_SCALA_VERSION=2.12 in load-spark-env.sh.
> ```
