Description

I see occasional failures (1 out of ~20) on branch 0.94 of TestSplitLogWorker#testAcquireTaskAtStartup

Running org.apache.hadoop.hbase.regionserver.TestSplitLogWorker
Tests run: 5, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 4.737 sec <<< FAILURE!
Failed tests:

Bisecting commits on 0.94 branch, using (up to) 50 repetitions to include or exclude, I get:

8cc5a5f481aeaf6debfa95110c4392d9c3ea20ca is the first bad commit
commit 8cc5a5f481aeaf6debfa95110c4392d9c3ea20ca
    HBASE-7172 TestSplitLogManager.testVanishingTaskZNode() fails when run individually and is flaky
