Description

The test fails very rarely on a laptop, but very commonly during Jenkins runs.

Error Message
  Flush thread did not run within 10 seconds
Stacktrace
java.lang.AssertionError: Flush thread did not run within 10 seconds
	at org.apache.hadoop.metrics2.sink.TestRollingFileSystemSinkWithHdfs.testFlushThread(TestRollingFileSystemSinkWithHdfs.java:291)

According to my test, this breaks about 0.3% locally.
