Which alternatives to ThriftServer do we really have? If ThriftServer is
not there anymore, there is no other way to connect to Spark SQL using

sparkSession.sessionState().sqlParser().parsePlan("select * from
myTable");
Afterwards you can implement your custom logic and execute it in this way:
Dataset ds =
