-------------------------------------
Summary: Impala does not allow the use of insecure clusters with
public IPs by default
Key: IMPALA-7182
URL: https://issues.apache.org/jira/browse/IMPALA-7182
Project: IMPALA
Issue Type: Documentation
Components: Security
Affects Versions: Impala 2.12.0
Reporter: Sailesh Mukil
Assignee: Alex Rodoni
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.
