Yes, the workaround is to create multiple StringIndexers as you described.
OneHotEncoderEstimator is only in Spark 2.3.0, you will have to use just
OneHotEncoder.

Hi,
So, what is the workaround? Should I create multiple indexer(one for each
column), and then create pipeline and set stages to have all the
StringIndexers?
I am using 2.2.1 as I cannot move to 2.3.0. Looks like
oneHotEncoderEstimator is broken, please see my email sent today with
subject:
OneHo
Multi column support for StringIndexer didn’t make it into Spark 2.3.0
The PR is still in progress I think - should be available in 2.4.0
