------------------------------
Summary: Hsync Metrics error
Key: HDFS-5355
URL: https://issues.apache.org/jira/browse/HDFS-5355
Project: Hadoop HDFS
Issue Type: Bug
Reporter: haosdent
Priority: Minor
The authors before comment "Expect two syncs, one from the hsync, one on close"
in TestDataNodeMetrics.java. In fact there isn't call sync when close. One
hsync call would produce two syncs, one for checksum and the other for block. I
modify relate code and make it looks like the hflush metrics.
