[SPARK-15492][ML][DOC] Binarization scala example copy & paste to spark-shell
error
## What changes were proposed in this pull request?
(Please fill in changes proposed in this fix)
The Binarization scala example val dataFrame : Dataframe =
spark.createDataFrame(data).toDF("label", "feature"), which can't be pasted in
the spark-shell as Dataframe is not imported. Compared with other examples,
this explicit type is not required.
So I removed Dataframe in the code.
## How was this patch tested?
(Please explain how this patch was tested. E.g. unit tests, integration tests,
manual tests)
