[KangTomwk]

在DSS上提交flink sql应用，现象如下：
（1）前端显示：ERROR Job with execId-IDE_linkis_flink_0 + subJobId : 159 execute failed,21304, Task is Failed,errorMsg: errCode: 12003 ,desc: cdh03:9101_0 Failed to async get EngineNode AMErrorException: errCode: 30002 ,desc: ServiceInstance(linkis-cg-engineconn, cdh03:36449) ticketID:ad3ba4cc-a06d-4f2e-afde-e8b64d3db83e 初始化引擎失败,原因: Failed to start EngineConn, reason: ECMErrorException: errCode: 11102 ,desc: Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=250m; support was removed in 8.0
（2）后台linkis-cg-engineconnmanager.log日志显示：

Error: Could not find or load main class org.apache.linkis.engineconn.launch.EngineConnServer

Look at final error message:"Error: Could not find or load main class org.apache.linkis.engineconn.launch.EngineConnServer". It seems like the lib directory of linkis-cg-engineconnmanager lack of JAR of EngineConnServer.
