Subject [jira] [Commented] (AIRAVATA-855) Error retrieving credentials for community user.gateway - nulltoken id - null - Warning message
Date Wed, 15 May 2013 21:51:22 GMT


Amila Jayasekara commented on AIRAVATA-855:

Hi Raman,

1 - This is fixed.

2. - Our current approach is not 100% correct. The idea is to store passwords also as credentials
and retrieve it from credential store. I wanted to make credential store work even with the
properties file as we are hurrying for the ultra scan deployment. We do not show this as a
error. This is just a warning. If you are concerned about long stack trace I can remove it.
But still the warning should be there.

3. Well I do not think error is misleading. If error is misleading then it has to come from
jdbc driver for mysql. I do not craft any error messages. I get error directly from SQL API.
Please attach your log file.

> I am getting " Error retrieving credentials for community user.gateway - nulltoken id
- null" warning message multiple times for a single job running in Airavata. My job works
fine but this warning messages is logged multiple time to the catalina.out. 
> I have 3 concerns regarding this message: 
> 1. Why we are calling credential store multiple times for a single request? We should
call it one from GFAC API or Airavata API and pass the credential to required places. We can
use SecurityContext in GFAC  to shared it with handlers and providers. 
> 2. As we have both the options to use credential store and property file (in current
version), we need not to show the warning all the time. We should make this configurable by
some flag. This is really important for GFAC unit test cases to pass without any warning message.

> 3. Cause of the warning is misleading "Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:
Table 'us3airavata.credentials' doesn't exist". I already have the table but not the credential
but the error is misleading.  
> I will attach the log file for more information.
