---------------------------------
Hi [~twalthr], Thanks a lot for the solution. Agree with you that we should
expose interfaces instead of implementations.
I have some quick questions and looking forward to your reply:
1. Regarding to the return type BatchTableEnvironment of the following API:
{code:java}
static BatchTableEnvironment getTableEnvironment(BatchEnvironment env);{code}
What's the package name of BatchTableEnvironment? Seems that the backwards
compatibility will always be broken no matter what it is.
2. The facade class for Batch/StreamTableEnvironment needs to consider for both
Scala and Java or we will have separate facade classes for Scala and Java?
