Hm, this looks possibly related to, but not the same as what was of concern
in 1247. In the client migration, there was some uncertainty in the
ElasticsearchSearchIntegrationTest. But this failure appears to be in the
indexing integration test. It's actually an error, not a normal failure. And it
appears to happen before any tests can start to run. Can you open a ticket? We
should track the intermittent failure, but I think it's unrelated to this PR.
Incidentally, I caught something in the logs I never noticed before. `90399
[main] INFO o.e.n.Node - version[5.6.2-SNAPSHOT], pid[21275],
build[Unknown/Unknown], OS[Linux/4.4.0-101-generic/amd64], JVM[Oracle
Corporation/Java HotSpot(TM) 64-Bit Server VM/1.8.0_151/25.151-b12]`. This
might also be worth looking into as I'm not sure if/why we should be depending
on a SNAPSHOT version.
