Fang-Yu Rao closed IMPALA-9021.
-------------------------------
    Resolution: Won't Fix

It is not really an issue since Impala sends an IPv6 address to the Ranger server.

> Currently on a Ranger-enabled Impala minicluster, Impala would produce a wrong value for the Ranger audit field of client IP after executing a SQL statement that triggers the check of authorization.
> Specifically, if a user issues a SQL statement '{{SHOW TABLE STATS functional.alltypes;}}', the value of the 3rd argument {{clientIp}} to the constructor of {{RangerBufferAuditHandler}} (https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/authorization/ranger/RangerAuthorizationChecker.java#L224) would be  '{{::ffff:127.0.0.1}}' (an IPv6 address) instead of '{{127.0.0.1}}' (an IPv4 address). This could be verified by attaching a Java debugger to {{impalad}} and observing the value of the 3rd argument {{clientIp}}.
