Solution:
This is because the versions of json4s in spark jars and json4s in linkis ujes spark enginemanager / lib package are inconsistent. When the official release is released, the supported versions of spark will be indicated later. If they are inconsistent, this problem will exist. The solution is to replace the json4s package in spark jars with the json4s version in the linkis ujes spark enginemanager / lib package. In addition, the netty package may have conflicts, which can be handled according to the method of json4s
