java.io.OutputStream

alluxio.underfs.hdfs.HdfsUnderFileOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

@NotThreadSafe
public class HdfsUnderFileOutputStream
extends OutputStream

Output stream implementation for HdfsUnderFileSystem. This class is just a wrapper on top of an underlying FSDataOutputStream, except all calls to flush() will be converted to FSDataOutputStream.sync(). This is currently safe because all invocations of flush intend the functionality to be sync.
