I'm using the below connection string but still getting the same "HTTP Response code: 401 (state=08S01,code=0)" error: Note: I do have a valid kerberos ticket for accessing the service. # beeline -u "jdbc:hive2://xxx.xxx.local:10001/;principal=hive/xxx.xxx.local@xxx.LOCAL;ssl=true;sslTrustStore=/opt/hdp/security/pki/certs-new/jks/truststore.jks;trustStorePassword=changeit;transportMode=http;httpPath=cliservice" Connecting to jdbc:hive2://xxx.xxx.local:10001/;principal=hive/xxx.xxx.local@xxx.LOCAL;ssl=true;sslTrustStore=/opt/hdp/security/pki/certs-new/jks/truststore.jks;trustStorePassword=changeit;transportMode=http;httpPath=cliservice 18/08/30 13:11:33 [main]: ERROR jdbc.HiveConnection: Error opening session org.apache.thrift.transport.TTransportException: HTTP Response code: 401 at org.apache.thrift.transport.THttpClient.flushUsingHttpClient(THttpClient.java:262) at org.apache.thrift.transport.THttpClient.flush(THttpClient.java:313) at org.apache.thrift.TServiceClient.sendBase(TServiceClient.java:73) at org.apache.thrift.TServiceClient.sendBase(TServiceClient.java:62) at org.apache.hive.service.cli.thrift.TCLIService$Client.send_OpenSession(TCLIService.java:158) at org.apache.hive.service.cli.thrift.TCLIService$Client.OpenSession(TCLIService.java:150) at org.apache.hive.jdbc.HiveConnection.openSession(HiveConnection.java:622) at org.apache.hive.jdbc.HiveConnection.<init>(HiveConnection.java:221) at org.apache.hive.jdbc.HiveDriver.connect(HiveDriver.java:105) at java.sql.DriverManager.getConnection(DriverManager.java:664) at java.sql.DriverManager.getConnection(DriverManager.java:208) at org.apache.hive.beeline.DatabaseConnection.connect(DatabaseConnection.java:146) at org.apache.hive.beeline.DatabaseConnection.getConnection(DatabaseConnection.java:211) at org.apache.hive.beeline.Commands.connect(Commands.java:1204) at org.apache.hive.beeline.Commands.connect(Commands.java:1100) 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.hive.beeline.ReflectiveCommandHandler.execute(ReflectiveCommandHandler.java:54) at org.apache.hive.beeline.BeeLine.dispatch(BeeLine.java:998) at org.apache.hive.beeline.BeeLine.initArgs(BeeLine.java:717) at org.apache.hive.beeline.BeeLine.begin(BeeLine.java:779) at org.apache.hive.beeline.BeeLine.mainWithInputRedirection(BeeLine.java:493) at org.apache.hive.beeline.BeeLine.main(BeeLine.java:476) 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.hadoop.util.RunJar.run(RunJar.java:233) at org.apache.hadoop.util.RunJar.main(RunJar.java:148) Error: Could not establish connection to jdbc:hive2://xxx.xxx.local:10001/;principal=hive/xxx.xxx.local@xxx.LOCAL;ssl=true;sslTrustStore=/opt/hdp/security/pki/certs-new/jks/truststore.jks;trustStorePassword=changeit;transportMode=http;httpPath=cliservice: HTTP Response code: 401 (state=08S01,code=0) Beeline version 1.2.1000.2.6.5.0-292 by Apache Hive 0: jdbc:hive2://xxx.xxx.local:10001/ (closed)> ...
