Re: Flink SQL questions


Usually, the problem occurs when users import the wrong classes. The current class naming is a bit confusing as there are 3 StreamTableEnvironment classes. You need to choose the one that matches your programming language. E.g. org.apache.flink.table.api.java.StreamTableEnvironment.

Hi Michael,

There are some test cases in Flink git, such as[1] which I think may help you.

I am trying to get a minimal Flink SQL program going to test it out.  I have a StreamExecutionEnvironment and from that created a StreamTableEnvironment.  The docs indicate there should be a fromDataStream method to create a Table, but none appears to exist according to Eclipse.  The method registerDataStream is also missing, just registerDataSteramInternal.  The Internal suggests private API to me, so I am asking if the docs are out of date, or I am missing some library or such.  I am using Java 8.0 not Scala.
