Auto-logSync based on edit log buffer size broken
-------------------------------------------------
Key: HDFS-3020
URL: https://issues.apache.org/jira/browse/HDFS-3020
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.23.0, 0.22.0
Reporter: Todd Lipcon
Priority: Critical
HDFS-1112 added a feature whereby the edit log automatically calls logSync() if
the buffered data crosses a threshold. However, the code checks
{{bufReady.size()}} rather than {{bufCurrent.size()}} -- which is incorrect
since the writes themselves go into {{bufCurrent}}.
