If the auth of Impala is 'noSasl' or 'Kerberos',this plugin will work fine.
But if the auth of Impala is 'none'(using password and username to connect Impala), kettle will report a error like picture1.
And the type of auth could not edit on the kettle's interface, kettle will report a error about 'duplicate key'.
So , I think the type of auth of Impala shoud be defined on the kettle's interface by user. I edited the code like this merge,the all problems are solved in my project.
