The Table API is a language-integrated API for Scala, Java and Python. Instead of specifying queries as String values as common with SQL, Table API queries are defined in a language-embedded style in Java, Scala or Python with IDE support Flink on Zeppelin Notebooks for Interactive Data Analysis - Part 2. 23 Jun 2020 Jeff Zhang ()In a previous post, we introduced the basics of Flink on Zeppelin and how to do Streaming ETL. Flink’s core is a streaming dataflow engine that provides data distribution, communication, and fault tolerance for distributed computations over data streams. Flink also builds batch processing on top of the streaming engine, overlaying native iteration support, managed memory, and program optimization. There will be compilation errors in tableEnv.registerFunction： "Found xx.xxx.TableFunc0，required org.apache.flink.table.functions.ScalarFunction"。 I did some testing, only Java users have this problem.

In local mode, for example when running your application from an IDE, you can configure log4j as usual, i.e. by making a log4j.properties available in the classpath.
