Hi @PauloRC @Tim Armstrong , This might be a performance regression, but also in general a performance inefficiency with a specific planner data structure. A correctness fix for IMPALA-8386 may have introduced this perf regression in 3.2.1, IMPALA-9358 may resolve this issue, but I don't think it's available in any CDH 6.3 release yet. @PauloRC one thing to try which might mitigate the issue is to run your view query with SET ENABLE_EXPR_REWRITES=false to see if that helps.

Thanks Darren! The situation was regarding having multiple SSL based ports exposed from the same role/instance. It worked with using additionalConfigs but as you mentioned just had to do a bit of magic to get it working correctly with passwords.

Can a Role in a CSD have multiple SSLServer sections associated with it? Or as an alternative could a single parameter map to more than one config entry?

The SSLServer Role in CSDs generates three parameters in the Cloudera Manager UI one for the private key, one for the certificate and another for the certificate chain. However at least in the case of PEM format SSLServer per https://github.com/cloudera/cm_ext/wiki/Service-Descriptor-Language-Reference#-sslserver only a single substitution and a single config name are available instead of three.
