Mark Miller commented on SOLR-6915:
-----------------------------------
bq. have you seen it at all on trunk yet?
I have not yet, but I've only looked at one or two of the fails from the
jenkins cluster.
On my local jenkins it has failed 5 out of 5 on 5x and passed about the same on
trunk. On my dev box (same env as jenkins box) 5x tests seem to run fine.

> We should provide a ZkACLProvider that requires SASL authentication. This
> provider will be useful for administration in a kerberos environment. In
> such an environment, the administrator wants solr to authenticate to
> zookeeper using SASL, since this is only way to authenticate with zookeeper
> via kerberos.
> The authorization model in such a setup can vary, e.g. you can imagine a
> scenario where solr owns (is the only writer of) the non-config znodes, but
> some set of trusted users are allowed to modify the configs. It's hard to
> predict all the possibilities here, but one model that seems generally useful
> is to have a model where solr itself owns all the znodes and all actions that
> require changing the znodes are routed to Solr APIs. That seems simple and
> reasonable as a first version.
> As for testing, I noticed while working on SOLR-6625 that we don't really
> have any infrastructure for testing kerberos integration in unit tests.
> Internally, I've been testing using kerberos-enabled VM clusters, but this
> isn't great since we won't notice any breakages until someone actually spins
> up a VM. So part of this JIRA is to provide some infrastructure for testing
> kerberos at the unit test level (using Hadoop's MiniKdc, HADOOP-9848).
