Gabor Bota commented on HDFS-13481:

It seems like changing the
org.apache.hadoop.metrics2.impl.MetricsConfig#QUEUE_CAPACITY_KEY value to 2
(the default is 1) fixes the issue. The default value is 1, and sometimes
org/apache/hadoop/metrics2/impl/MetricsSinkAdapter's queue can not accept an
additional element, so RollingFileSystemSink#testFlushThread
RollingFileSystemSink is not able to flush the dropped element.
I will provide a patch soon.
