List of blockReceived() Examples

Examples of blockReceived()

org.apache.hadoop.hdfs.server.protocol.DatanodeProtocol.blockReceived()
blockReceived() allows the DataNode to tell the NameNode about recently-received block data, with a hint for pereferred replica to be deleted when there is any excessive blocks. For example, whenever client code writes a new Block here, or another DataNode copies a Block to this DataNode, it will call blockReceived().

Examples of org.apache.hadoop.hdfs.server.protocol.DatanodeProtocol.blockReceived()

    Block[] blocks = new Block[] { block };
    String[] delHints = new String[] { "" };
    
    // Ensure blockReceived call from dead datanode is rejected with IOException
    try {
      dnp.blockReceived(reg, blocks, delHints);
      Assert.fail("Expected IOException is not thrown");
    } catch (IOException ex) {
      // Expected
    }
