  1. Hadoop Common
  2. HADOOP-12177 [Umbrella] Update and extend filesystem specification
  3. HADOOP-13327

Add OutputStream + Syncable to the Filesystem Specification

    XMLWordPrintableJSON

Details

    Description

      Write down what a Filesystem output stream should do. While core the API is defined in Java, that doesn't say what's expected about visibility, durability, etc —and Hadoop Syncable interface is entirely ours to define.
