Kihwal Lee created HDFS-4191:
--------------------------------
Summary: Track new transactions per thread so that unnecessary
logSync() calls can be avoided
Key: HDFS-4191
URL: https://issues.apache.org/jira/browse/HDFS-4191
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 3.0.0
Reporter: Kihwal Lee
Assignee: Kihwal Lee
With this fix, logSync() can be called anytime by a thread without affecting
the batched syncs metrics. As discussed in HDFS-4186, we will put this feature
only to trunk first and let it soak for some time.
