> Key: IMPALA-7182
> URL: https://issues.apache.org/jira/browse/IMPALA-7182
> Project: IMPALA
> Issue Type: Task
> Components: Security
> Affects Versions: Impala 2.12.0
> Reporter: Sailesh Mukil
> Assignee: Alex Rodoni
> Priority: Critical
> Labels: docs, security
> Fix For: Impala 3.1.0
>
>
> We made Impala more secure by using KRPC which doesn't allow the usage of
> insecure clusters (no auth or no encryption) with public IPs by default.
> We have a workaround which is to add the subnet to this flag
> 'trusted_subnets':
> https://github.com/apache/impala/blob/master/be/src/kudu/rpc/server_negotiation.cc#L70-L80
> Although we don't expect users to run production environments with this
> configuration, we need to document this as it's a slight behavioral change
> from Impala 2.11 to Impala 2.12.
