> Client tools, such as Canary, which make use of keytab based logins with AuthUtil.getAuthChore()
do not allow any way to continue without a keytab-based login when security is enabled.  Currently,
when security is enabled and the configuration lacks {{hbase.client.keytab.file}}, these tools
would fail with:
> {noformat}
> ERROR hbase.AuthUtil: Error while trying to perform the initial login: Running in secure
mode, but config doesn't have a keytab

> These tools should still work with the default credential-cache login, at least when
a client keytab is not configured.
