             Summary: Update documentation - QuickStart - FlinkML
                 Key: FLINK-4792
                 URL: https://issues.apache.org/jira/browse/FLINK-4792
             Project: Flink
          Issue Type: Improvement
            Reporter: Thomas FOURNIER
            Priority: Trivial


Hi,

I'm going through the first steps of FlinkML/QuickStart guide: https://ci.apache.org/projects/flink/flink-docs-release-1.2/dev/libs/ml/quickstart.html

When using env.readCsvFile:

val env = ExecutionEnvironment.getExecutionEnvironment
val survival = env.readCsvFile[(String, String, String, String)]("path/data")

I encounter the following error:

Error:(17, 69) could not find implicit value for evidence parameter of type org.apache.flink.api.common.typeinfo.TypeInformation[(String, String, String, String)]
Error occurred in an application involving default arguments.
val survival = env.readCsvFile[(String, String, String, String)]("path/data")

To solve this issue, you need to do the following imports:

import org.apache.flink.api.scala._  ( instead of import org.apache.flink.api.scala.ExecutionEnvironment as documented).

I think it would be relevant to update the documentation, even if this point is mentioned in FAQ.

Thanks

Best

Thomas
