Hi, within the Flink Interpreter context, we try to get a Batch TableEnvironment with the following code. The code was executed within a Apache Zeppelin paragraph.
[code] import org.apache.flink.table.api._ import org.apache.flink.table.api.scala._ import org.apache.flink.table.sources._ val batchEnvironment = benv val batchTableEnvironment = TableEnvironment.getTableEnvironment (batchEnvironment) [/code] When executing the paragraph, we get the following error. [error] Caused by: java.lang.ExceptionInInitializerError: java.lang.NullPointerException Caused by: java.lang.NullPointerException at org.apache.flink.table.api.scala.BatchTableEnvironment.<init> (BatchTableEnvironment.scala:47) at org.apache.flink.table.api.TableEnvironment$.getTableEnvironment (TableEnvironment.scala:1049) [/error] Any ideas why there is the NullPointerException? I am grateful for any ideas.
