Subject Flink Table & SQL doesn't work in very simple example
Date Wed, 22 Jun 2016 01:52:08 GMT
Hi,


I’m trying to use Flink Table 1.1-SNAPSHOT where I want to use Table API and SQL in my project.
But when I run the very simple example WordCountTable, I encountered the following exception
: 

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.calcite.rel.logical.LogicalAggregate.getGroupSets()Lorg/apache/flink/shaded/com/google/common/collect/ImmutableList;

It seems that something  wrong with our guava shade. Do you have any ideas? 

My pom file and WordCountTable.scala are here: https://gist.github.com/wuchong/9c1c0df3cb7453502abc4605f5347289

And I found someone have the same problem on stack overflow: http://stackoverflow.com/questions/37835408/org-apache-flink-api-table-tableexception-alias-on-field-reference-expression-e#comment63160086_37838816
