[jira] [Created] (IMPALA-5804) Avoid expensive fork for kinit

Sailesh Mukil created IMPALA-5804:
-------------------------------------

             Summary: Avoid expensive fork for kinit
                 Key: IMPALA-5804
                 URL: https://issues.apache.org/jira/browse/IMPALA-5804
             Project: IMPALA
          Issue Type: Improvement
          Components: Security
    Affects Versions: Impala 2.9.0
            Reporter: Sailesh Mukil
            Assignee: Sailesh Mukil
            Priority: Critical


Impala currently kinits by forking off a subprocess. This has proved to be expensive in many cases since the subprocess tries to reserve as much memory as Impala is currently using which can be quite a lot.
