[jira] [Created] (FLINK-20918) Avoid excessive flush of Hadoop
output stream
Paul Lin created FLINK-20918:
--------------------------------
Summary: Avoid excessive flush of Hadoop output stream
Key: FLINK-20918
URL: https://issues.apache.org/jira/browse/FLINK-20918
Project: Flink
Issue Type: Bug
Affects Versions: 1.11.3, 1.12.0
Reporter: Paul Lin
[HadoopRecoverableFsDataOutputStream#sync|https://github.com/apache/flink/blob/67d167ccd45046fc5ed222ac1f1e3ba5e6ec434b/flink-filesystems/flink-hadoop-fs/src/main/java/org/apache/flink/runtime/fs/hdfs/HadoopRecoverableFsDataOutputStream.java#L123] calls both `hflush` and `hsync`, whereas `hsync` is an enhanced version of `hflush`. We should remove the `hflush` call to avoid the excessive flush.
