The issue here is that disruptions are not always fully healed when the test ends, which leads to failures in clean-up actions. @DaveCTurner thoughts on how to ensure this?

Another failure encountered here: https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+7.x+periodic/486/console

Reproduce with:

./gradlew :server:integTest --tests "org.elasticsearch.discovery.ClusterDisruptionIT.testAckedIndexing" \
  -Dtests.seed=D0453D059CF4F8AE \
  -Dtests.security.manager=true \
  -Dtests.locale=hr-HR \
  -Dtests.timezone=Pacific/Wake \
  -Dcompiler.java=12 \
  -Druntime.java=8

Couldn't reproduce locally.

The message is different though:

org.elasticsearch.discovery.ClusterDisruptionIT > testAckedIndexing FAILED
    java.lang.AssertionError: [test][2], node[kWppasG3RSKIRbBheOdOVA], [R], s[STARTED], a[id=SxfxSm_6Q3KWu6VDYMA0bQ] global checkpoint syncs mismatch

         but: was <4L>

@matriv I've figured out your failure. The issue was that the global checkpoint sync interval was not correctly reduced for testAckedIndexing. This is fixed in d49d9b5 /cc: @dnhatn

[dnhatn]

Thanks @ywelsch.

Backported this to 7.2 too, since these test-failures still show up here and this was clearly intended to go there too.

Closing this as this issue mixed various unrelated test failures. With the most recent one being fixed, and the prior one not having shown up recently, I prefer to close this issue and instead have a new issue created once we get a newer failure.
