> Streamline the kerberos logic in thin client java code

>                 Key: PHOENIX-5772
>                 URL:
>             Project: Phoenix
>          Issue Type: Task
>          Components: queryserver
>            Reporter: Istvan Toth
>            Assignee: Istvan Toth
>            Priority: Major
>          Time Spent: 10m
>  Remaining Estimate: 0h
> The thin client has logic for sqlline-thin that automatically enablies SPNEGO based on
hbase and hadoop settings and whether or not the user is is logged into kerberos.
> According to my analysis, this is the only feature that this code provides. 
> When using the JAR as a JDBC driver, the kerberos code does not apply.
> However, this feature depends on hadoop, which carries the heavy cost bloating the thin
client size and polluting its classpath.
> I propose removing the the feature from the Java code, and potentially implementing it
in the sqlline-thin startup script.
> This would cut the JAR size by ~80%, and solve a lot of classpath problems for the users
of the JDBC driver.
> This is based on discussion with [~elserj] during the review of PHOENIX-5761
