Henning Kropp updated CASSANDRA-7083:
-------------------------------------
Attachment: auth_cql.patch
patch/workaround for {{cassandra-1.2.15}}
The here given patch is more a workaround than a real patch as it just copies
the code from {{CqlStorage}} and only works if username and password are given
in the conf. Works for us for now.
> Authentication Support for CqlRecordWriter
> ------------------------------------------
>
> Key: CASSANDRA-7083
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7083
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Reporter: Henning Kropp
> Labels: authentication, pig
> Attachments: auth_cql.patch

>
> The {{CqlRecordWriter}} seems not to support authentication. When the
> keyspace in Cassandra is to set to use authentication our Pig job fails with,
> when credentials are provided using the URI ('cql://username:password...):

> If not supplied in the URI but as a {{JobConf}} the exception:

> Output Location Validation Failed for: 'cql://...' More info to follow:

> at org.apache.pig.newplan.logical.rules.InputOutputFileValidator$
> {code}
> Which let to the finding, that authentication is correctly supplied for
> {{CqlStorage}} but not for the {{CqlRecordWriter}}.
> May be it would make sense to put the authentication part into
> {{ConfigHelper.getClientFromAddressList()}}? Then in {{CqlStorage} the
> username and password in the conf would need to be set from the URI. If so
> the {{ConfigHelper}} has all the information to authenticate and already
> returns the client.
