-----------------------------------------------------------
[~straw] I checked the hive-exec-2.2.0.jar, there's no orc-core class. But it
seems the docuement is misleading, I think you can use orc-core-1.5.6.jar.
Hopes it can help.
The reason is the [flink-connector-hive] requires [flink-orc] to write orc
formats, but [flink-orc] requires orc-core with a version of 1.5.6.
