Hi, All, We are using Hive 1.1.0 on CDH 5.12 and I'm new to Hive.
Our client app imports data from Oracle DB to Hive. The logic is like this: get a connection to hive then execute some SQL statement //the error occurs here After importing several tables successfully, we got following error thrown by Hiveserver2: Caused by: org.apache.hive.service.cli.HiveSQLException: Invalid SessionHandle: SessionHandle [26eaeddc-ce90-4c6f-8a67-a6a886a7defe] at org.apache.hive.service.cli.session.SessionManager.getSession( SessionManager.java:432) at org.apache.hive.service.cli.CLIService.executeStatementAsync(CLIService.java:282) at org.apache.hive.service.cli.thrift.ThriftCLIService.ExecuteStatement(ThriftCLIService.java:501) at org.apache.hive.service.cli.thrift.TCLIService$Processor$ExecuteStatement.getResult(TCLIService.java:1313) at org.apache.hive.service.cli.thrift.TCLIService$Processor$ExecuteStatement.getResult(TCLIService.java:1298) at org.apache.thrift.ProcessFunction.process(ProcessFunction.java:39) at org.apache.thrift.TBaseProcessor.process(TBaseProcessor.java:39) at org.apache.hadoop.hive.thrift.HadoopThriftAuthBridge$Server$TUGIAssumingProcessor.process(HadoopThriftAuthBridge.java:746) at org.apache.thrift.server.TThreadPoolServer$WorkerProcess.run(TThreadPoolServer.java:286) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) It looks like the session was closed by the Hive server, but I don't find any related log in the Hive log files. (the log level is set to 'DEBUG') I know the Hive server will close the expired session, but I didn't see the related log. Is there any other cases that the session handler will be closed (i.e. The SessionMananger.closeSession() is called)? and does anyone know how to debug this issue?
