Subject Re: Why application is parsed twice
Date Sun, 21 Dec 2014 18:18:59 GMT
Hi Udara,

Thanks for the information, I see the below logic
in DefaultApplicationParser:

private ApplicationClusterContext createApplicationClusterContext ()
            throws ApplicationDefinitionException {
        ...
        String oAuth_token = createToken(appId);
        payloadData.add(TOKEN_PAYLOD_PARAM_NAME, oAuth_token);

        String textPayload = payloadData.toString();
        return new ApplicationClusterContext(cartridgeInfo.getType(),
clusterId, hostname, textPayload, deploymentPolicy, isLB);
    }

Shouldn't this happen once per application? As it looks like now an OAuth
token is generated per cluster. Is this necessary?

Thanks
