Tzu-Li (Gordon) Tai reopened FLINK-6173:
----------------------------------------
> flink-table not pack-in com.fasterxml.jackson.* in after #FLINK-5414
> --------------------------------------------------------------------
>
> Key: FLINK-6173
> URL: https://issues.apache.org/jira/browse/FLINK-6173
> Project: Flink
> Issue Type: Bug
> Components: Table API & SQL
> Reporter: Zhenghua Gao
> Assignee: Timo Walther
> Priority: Blocker
> Fix For: 1.4.0, 1.3.4
>
>
> Currently, flink-table will pack-in com.fasterxml.jackson.* and rename them
> to org.apache.flink.shaded.calcite.com.fasterxml.jackson.*
> If a project depends on flink-table, and uses fasterxml as follows(function
> explain uses fasterxml indirectly):
> {code:title=WordCount.scala|borderStyle=solid}
> object WordCountWithTable {
> def main(args: Array[String]): Unit = {
> // set up execution environment
> val env = ExecutionEnvironment.getExecutionEnvironment
> val tEnv = TableEnvironment.getTableEnvironment(env)
> val input = env.fromElements(WC("hello", 1), WC("hello", 1), WC("ciao",
> 1))
> val expr = input.toTable(tEnv)
> val result = expr
> .groupBy('word)
> .select('word, 'frequency.sum as 'frequency)
> .filter('frequency === 2)
> println(tEnv.explain(result))
> result.toDataSet[WC].print()
> }
> case class WC(word: String, frequency: Long)
> }
> {code}
> It actually uses org.apache.flink.shaded.calcite.com.fasterxml.jackson.*
> I found after FLINK-5414, flink-table didn't pack-in com.fasterxml.jackson.*
> and the project would throw class not found exception.
