-------------------------------------

             Summary: Avoid fork for kinit
                 Key: IMPALA-5129
                 URL: https://issues.apache.org/jira/browse/IMPALA-5129
             Project: IMPALA
          Issue Type: Improvement
          Components: Security
            Reporter: Sailesh Mukil
            Assignee: Sailesh Mukil


Impala does a kinit by doing a RunShell() command which basically forks the entire process
(potentially expensive) and execs the 'kinit' command.

KuduRPC avoids the fork by calling into libkrb programatically. Since we eventually will be
pulling in KuduRPC to Impala, we can get rid of the fork and call into the appropriate KuduRPC
code.
