I keep getting following error message   Status : Failure -Test failed: [Cloudera][HiveJDBCDriver](500164) Error initialized or created transport for authentication: [Cloudera][HiveJDBCDriver](500169) Unable to connect to server: GSS initiate failed.   My Hadoop environment has Hive version 1.2.1.2.3 Kerberos version 1.10.3-10 I am trying to connect to this Hive database from Windows 7 64-bit machine which has Sqldeveloper version 4.2.0.16.356.1154 Cloudera_Hive JDBC4 driver 2.5.18.1050 MIT Kerberos app version 4.1   Important: Windows machine I am connecting from is on a different domain as that of Hadoop cluster.   I have followed instructions from Using SQL Developer to access Apache Hive with kerberos authentication and steps I have performed are. Imported all the jar files to SQL Developer from the JDBC driver . Updated Java Crypto jars (local_policy.jar and US_export_policy.jap in sqldeveloper\jdk\jre\lib\security folder) with ones provided in UnlimitedJCEPolicy.zip. Created an environment variable  KRB5CCNAME whose value is set to C:\sqldeveloper\ktfile.keytab Installed MIT kerberos 4.1 64-bit app Acquired valid ticked (via kinit/hrough the app) Picture below shows the connection details Hive connection details were:     Host name: machine.test.group port: 10010 database: default Krbservicename: hive AuthMech: 1 KrbFQDN: machine.test.group KrbRealm:  dev.mycompany.com   Can someone please advise me what I can do to fix the issue and connect to Hive using JDBC drivers. ...
