Zhenghua Gao created FLINK-6173:
-----------------------------------
Summary: 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
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):
```
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)
}
```
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.
