----------------------------------
Summary: AtomicFileOutputStream should override FilterOutputStream
batch write API
Key: HDFS-17875
URL: https://issues.apache.org/jira/browse/HDFS-17875
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Ivan Andika
[~XiChen] found that AtomicFileOutputStream write is slow because the `
write(byte b[], int off, int len)` uses FilterOutputStream implementation which
calls write(byte b) for each byte.
We should override this API and forward it to the underlying OutputStream
instead.
