----------------------------------
I see something weird in there:

{code}
Why is one node seeing a live_nodes size 3, and the others seeing size 5? How
many are there supposed to be? I've suspected for a while there's some
weirdness involving live_nodes tracking, but I haven't been able to pin it down.

> http://jenkins.thetaphi.de/job/Lucene-Solr-6.x-Solaris/32/consoleText
> Checking out Revision c46d7686643e7503304cb35dfe546bce9c6684e7
> (refs/remotes/origin/branch_6x)
> Using Java: 64bit/jdk1.8.0 -XX:+UseCompressedOops -XX:+UseG1GC
> {noformat}
> The failure happened during the static setup of the test, when a
> MiniSolrCloudCluster & several clients are initialized -- before any code
> related to TolerantUpdateProcessor is ever used.
> I can't reproduce this, or really make sense of what i'm (not) seeing here in
> the logs, so i'm filing this jira with my analysis in the hopes that someone
> else can help make sense of it.
