             Summary: Revise ambiguous error message from load-spark-env.sh
                 Key: SPARK-26076
                 URL: https://issues.apache.org/jira/browse/SPARK-26076
             Project: Spark
          Issue Type: Improvement
          Components: Build
    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.
```
