3 years ago I try to modify SpringCloudFeignConfigurationCache code to find the reason of nullpointexception, I found that
DataWorkCloudApplication.getApplicationContext()
get null result!
DSS1.0、Linkis1.0.2 complie with scala2.12、spark3.1.2、hadoop3.1.1、hive3.1.0
the actual log :
Exception in thread "main" java.lang.NullPointerException at com.webank.wedatasphere.linkis.rpc.sender.SpringCloudFeignConfigurationCache$.getClient(SpringCloudFeignConfigurationCache.scala:73) at com.webank.wedatasphere.linkis.rpc.sender.SpringMVCRPCSender.doBuilder(SpringMVCRPCSender.scala:49) at com.webank.wedatasphere.linkis.rpc.BaseRPCSender.newRPC(BaseRPCSender.scala:67) at com.webank.wedatasphere.linkis.rpc.BaseRPCSender.getRPC(BaseRPCSender.scala:54) at com.webank.wedatasphere.linkis.rpc.BaseRPCSender.send(BaseRPCSender.scala:105) at com.webank.wedatasphere.linkis.engineconn.callback.service.AbstractEngineConnStartUpCallback.callback(EngineConnCallback.scala:39) at com.webank.wedatasphere.linkis.engineconn.callback.hook.CallbackEngineConnHook.afterEngineServerStartFailed(CallbackEngineConnHook.scala:64) at com.webank.wedatasphere.linkis.engineconn.launch.EngineConnServer$.$anonfun$main$16(EngineConnServer.scala:64) at com.webank.wedatasphere.linkis.engineconn.launch.EngineConnServer$.$anonfun$main$16$adapted(EngineConnServer.scala:64) at scala.collection.IndexedSeqOptimized.foreach(IndexedSeqOptimized.scala:36) at scala.collection.IndexedSeqOptimized.foreach$(IndexedSeqOptimized.scala:33) at scala.collection.mutable.ArrayOps$ofRef.foreach(ArrayOps.scala:198) at com.webank.wedatasphere.linkis.engineconn.launch.EngineConnServer$.main(EngineConnServer.scala:64) at com.webank.wedatasphere.linkis.engineconn.launch.EngineConnServer.main(EngineConnServer.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.spark.deploy.JavaMainApplication.start(SparkApplication.scala:52) at org.apache.spark.deploy.SparkSubmit.org$apache$spark$deploy$SparkSubmit$$runMain(SparkSubmit.scala:951) at org.apache.spark.deploy.SparkSubmit.doRunMain$1(SparkSubmit.scala:180) at org.apache.spark.deploy.SparkSubmit.submit(SparkSubmit.scala:203) at org.apache.spark.deploy.SparkSubmit.doSubmit(SparkSubmit.scala:90) at org.apache.spark.deploy.SparkSubmit$$anon$2.doSubmit(SparkSubmit.scala:1039) at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:1048) at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)
