Ishan Chattopadhyaya resolved SOLR-13942.
-----------------------------------------
Fix Version/s: 8.5
Resolution: Fixed
bq. I disagree with your statement above that the community's position is "No
data in ZK is private". To the contrary, in the ref-guide itself we suggest to
users that there are valid reasons to control ZK read access.
Ref guide says, "You might even want to limit read-access, if you think there
is stuff in ZooKeeper that not everyone should know about. Or you might just in
general work on a need-to-know basis". The endpoint that we have today can't be
locked down using authentication; this new endpoint can be.
bq. Redundant Functionality - Our Solr distribution already offers a handful of
ways to access ZK data. bin/solr, zkcli.sh, the /admin/zookeeper endpoint,
various Collections API commands, etc. And where these aren't
available/sufficient, there are plenty of external ZK clients to use.
bin/solr and zkcli.sh require direct access to ZK, and hence insecure.
/admin/zookeeper is ugly, and this one is not; I'm +1 to deprecating that one
in favour of this one. External ZK clients again need access to ZK, which is
insecure.
bq. Slimness Concerns - I'm a little surprised honestly that you and Ishan have
taken this up, when you've been so instrumental in getting people focused on
slimming Solr down and cutting everything out of core that's not related to
Solr's raison d'etre.
This issue is totally unrelated to that goal (which we'll continue to follow).
