Larry McCay commented on HADOOP-12554:
--------------------------------------
[~steve_l] - I'm taking a look at this today and just want to make sure that I
am considering the right change...
SwiftRestClient uses RestClientBindings to create the expected Properties
instance from the Hadoop configuration object.
I am considering adding a new method to RestClientBindings to for copyPassword
which will use Configuration.getPassword rather than Configuration.get to
extract the value from config.
We will then replace the following calls in the bind method with copyPassword:
{code}
copy(conf, prefix + DOT_USERNAME, props, SWIFT_USERNAME_PROPERTY, true);
copy(conf, prefix + DOT_APIKEY, props, SWIFT_APIKEY_PROPERTY, false);
copy(conf, prefix + DOT_PASSWORD, props, SWIFT_PASSWORD_PROPERTY,
props.contains(SWIFT_APIKEY_PROPERTY) ? true : false);
{code}
This will allow for backward compatibility to values in config but the ability
to override that with CredentialProvider stored credentials.
I don't happen to see any analogue to the S3 ability to provide the credentials
as part of the userInfo in the URI.
It is possible that I have missed it though.
Does this sound right?
