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; at org.apache.flink.api.table.plan.rules.dataSet.DataSetAggregateRule.matches(DataSetAggregateRule.scala:47) at org.apache.calcite.plan.volcano.VolcanoRuleCall.matchRecurse(VolcanoRuleCall.java:269) at org.apache.calcite.plan.volcano.VolcanoRuleCall.match(VolcanoRuleCall.java:253) at org.apache.calcite.plan.volcano.VolcanoPlanner.fireRules(VolcanoPlanner.java:1542) at org.apache.calcite.plan.volcano.VolcanoPlanner.registerImpl(VolcanoPlanner.java:1817) at org.apache.calcite.plan.volcano.VolcanoPlanner.register(VolcanoPlanner.java:1038) at org.apache.calcite.plan.volcano.VolcanoPlanner.ensureRegistered(VolcanoPlanner.java:1058) at org.apache.calcite.plan.volcano.VolcanoPlanner.changeTraits(VolcanoPlanner.java:723) at org.apache.calcite.tools.Programs$RuleSetProgram.run(Programs.java:331) at org.apache.flink.api.table.BatchTableEnvironment.translate(BatchTableEnvironment.scala:250) at org.apache.flink.api.scala.table.BatchTableEnvironment.toDataSet(BatchTableEnvironment.scala:139) at org.apache.flink.api.scala.table.TableConversions.toDataSet(TableConversions.scala:41) at com.alibaba.flink.examples.WordCountTable$.main(WordCountTable.scala:43) at com.alibaba.flink.examples.WordCountTable.main(WordCountTable.scala) 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 <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 <http://stackoverflow.com/questions/37835408/org-apache-flink-api-table-tableexception-alias-on-field-reference-expression-e#comment63160086_37838816> - Jark Wu
