["Tim Armstrong (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IMPALA-9367?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Armstrong resolved IMPALA-9367.
-----------------------------------
    Resolution: Won't Do

I don't think this is viable at this point because of the need to interoperate with the JVM side of things.

> Currently --krb5_ccname defaults to "/tmp/krb5cc_impala_internal" and requires that the argument be an absolute path.
> Kudu actually defaults to "MEMORY:kudu" as its credential cache, which may have some advantages, e.g. it doesn't depend on the filesystem.
> It would be reasonable to allow setting the credential cache type to MEMORY.
