> 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
> Priority: Major
> Labels: pull-request-available
>
> [~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.
