moonkev / impala-jdbc-kerberos Goto Github PK

Based on https://github.com/cmconner156/hiveserver2-jdbc-kerberos, modified to connect to Cloudera Impala CDH4.5.0 secure cluster.

To run this, do the following:

• Export keytab of the local principal, using 'hdfs' principal in this example kadmin.local xst -k hdfs.keytab hdfs/[email protected]
• Edit gss-jaas.conf to have the correct principal and path to keytab of that principal.
• Edit the krb5.conf with the correct values or copy one of your own over it. -- Alternatively you may just refer to /etc/krb5.conf
• Make sure you are using oracle's JDK in your path.
• Compile the project with Maven3 mvn clean install
• /usr/java/default/bin/java -cp target/hiveserver2-jdbc-1.0-jar-with-dependencies.jar com.test.ImpalaJDBC "jdbc:hive2://impala-host:21050/;principal=impala/[email protected]" /etc/krb5.conf

Notice that we are using local principal "[email protected]" to connect to impala using service principal impala/[email protected]
