Description

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:

ERROR hbase.AuthUtil: Error while trying to perform the initial login: Running in secure mode, but config doesn't have a keytab
java.io.IOException: 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.
