DFSOutputStream.sync should not be synchronized
-----------------------------------------------
Key: HDFS-3280
URL: https://issues.apache.org/jira/browse/HDFS-3280
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs client
Affects Versions: 2.0.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
HDFS-895 added an optimization to make hflush() much faster by unsynchronizing
it. But, we forgot to un-synchronize the deprecated {{sync()}} wrapper method.
This makes the HBase WAL really slow on 0.23+ since it doesn't take advantage
of HDFS-895 anymore.
