> Recent changes with BucketCachePersister caused this unit test  [TestVerifyBucketCacheFile.testRetrieveFromFile()|https://ci-hbase.apache.org/job/HBase-PreCommit-GitHub-PR/job/PR-5222/3/testReport/org.apache.hadoop.hbase.io.hfile.bucket/TestVerifyBucketCacheFile/precommit_checks___yetus_jdk8_Hadoop2_checks___testRetrieveFromFile_1__blockSize_16_384__bucketSizes__I_1151e434_/] to become flaky.
> The BucketCachePersister thread keeps running even after BucketCache.shutdown() is run and we do not clear the contents of the backingMap during the shutdown if cache persistence is enabled causing this test to fail. BucketCachePersister should be interrupted in BucketCache.shutdown().
