Package alluxio.underfs.hdfs

Class HdfsUnderFileOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    @NotThreadSafe
public class HdfsUnderFileOutputStream
extends java.io.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.
