Make possible to authenticate user when loading data to Cassandra with
BulkRecordWriter.
----------------------------------------------------------------------------------------
Key: CASSANDRA-4155
URL: https://issues.apache.org/jira/browse/CASSANDRA-4155
Project: Cassandra
Issue Type: Improvement
Reporter: Michał Michalski
Priority: Minor
I need to use the authorization feature (i.e. provided by SimpleAuthenticator
and SimpleAuthority). The problem is that it's impossible now to pass the
credentials (cassandra.output.keyspace.username and
cassandra.output.keyspace.passwd) to org.apache.cassandra.hadoop.ConfigHelper
because of no setters for these variables. Moreover, even if they could be
passed, nothing will change because they are unused - ExternalClient class from
org.apache.cassandra.hadoop.BulkRecordWriter is not making use of them; it's
not even receiving them and no authorization is provided.
The proposed improvement is to make it possible to authenticate user when
loading data to Cassandra with BulkRecordWriter by adding appropriate setters
to ConfigHelper and then passing credentials to ExternalClient class so it
could use it for authorization request.
I have created a patch for this which I attach.
This improvement was made in the way that does not charm existing
ExternalClient interface, but I think that it would be a bit nicer way to call
the new constructor every time (optionally with username and password set to
null) and keeping the old one "just in case", instead of having and using two
different constructors in two different cases. However, it's my first patch for
Cassandra, so I submit a less "agressive" one and I'm waiting for suggestions
for to modify it :)
