title: Configuring Kerberos authentication to run Impala queries as part of test automation in Jenkins build
body: <p>We have a module of java-Spark code that runs impala queries. As part of automation, i would like to have a junit that runs impala queries and compares the results with expected. Here the issue is need to pass through kerberos authentication to be able to run the impala queries in Jenkins. 
  One possible way I can think is install Kerberos client on Jenkins ,create ticket manually and place it in cache. Have that junit use the ticket in cache file for authentication
  Can anyone please tell me if there is any better alternative?</p>
