More info to follow: > InvalidRequestException(why:You have not logged in) > 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}}. > Maybe 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
