-------------------------------
Summary: Remove unnecessary hflush from log aggregation
Key: YARN-448
URL: https://issues.apache.org/jira/browse/YARN-448
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 0.23.7, 2.0.4-beta
Reporter: Kihwal Lee
Assignee: Kihwal Lee
AggregatedLogFormat#writeVersion() calls hflush() after writing the version.
Calling hflush does not seem to be necessary. It can add a lot of load to hdfs
in a big busy cluster.
