linkis 调用spark 问题

[肖培栋]

linkis 1.0.3 版本

spark spark-2.4.5-bin-hadoop2.7


出现报错内容：Job with execId-IDE_admin_spark_8 and subJobId : 9 from orchestrator 
completed with state ErrorExecuteResponse(21304, Task is Failed,errorMsg: 
errCode: 12003 ,desc: hadoop1:9101_8 Failed  to async get EngineNode

linkis-cg-linkismanager ,ip: hadoop1 ,port: 9104 ,serviceKind: 
linkis-cg-entrance,null)


 
查看 json4s 的版本都一致，问题出在哪里呢
