-------------------------------------
Summary: Client tools relying on AuthUtil.getAuthChore() break
credential cache login
Key: HBASE-17827
URL: https://issues.apache.org/jira/browse/HBASE-17827
Project: HBase
Issue Type: Bug
Components: canary, security
Reporter: Gary Helmling
Assignee: Gary Helmling
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}

in secure mode, but config doesn't have a keytab

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