Alessandro Solimando commented on HIVE-25929:
---------------------------------------------
I agree that any form of double negation should be avoided, so a "direct"
property name like "hive.conf.propagate.exec.engines" sounds way better.
Regarding the default value, I'd be inclined to include S3+Azure properties
there by default, for the following reason:
we know that the secure setup for accessing remote storages is via the "hadoop
credentials".
If credentials are put in the XML config, we are in a less secure setting
already, probably for experimenting.
For this less secure setting, I think we should make things easier for the end
user, avoiding them the extra step of overriding
"hive.conf.propagate.exec.engines".
Of course it's not a blocker, I am fine with a default value '' if you think
it's the best way to proceed.

> Project: Hive
> Issue Type: Bug
> Reporter: László Bodor
> Assignee: László Bodor
> Priority: Major
>
> History in chronological order:
> HIVE-10508: removed some passwords from config that's propagated to execution
> engines
> HIVE-9013: introduced hive.conf.hidden.list, which is used instead of the
> hardcoded list in HIVE-10508
> the problem with HIVE-9013 is it's about to introduce a common method for
> removing sensitive data from Configuration, which absolutely makes sense in
> most of the cases (set command showing sensitive data), but can cause issues
> e.g. while using non-secure cloud connectors on a cluster, where instead of
> the hadoop credential provider API (which is considered the secure and proper
> way), passwords/secrets appear in the Configuration object (like:
> "fs.azure.account.oauth2.client.secret")
> 2 possible solutions:
> 1. introduce a new property like: "hive.conf.hidden.list.exec.engines" ->
> which defaults to "hive.conf.hidden.list" (configurable, but maybe just more
> confusing to users, having a new config property which should be understood
> and maintained on a cluster)
> 2. simply revert DAGUtils to use to old stripHivePasswordDetails introduced
> by HIVE-10508 (convenient, less confusing for users, but cannot be configured)
