List of injectBlocks() Examples

Examples of injectBlocks()

org.apache.hadoop.dfs.SimulatedFSDataset.injectBlocks()
org.apache.hadoop.hdfs.MiniDFSCluster.injectBlocks()
This method is valid only if the data nodes have simulated data @param dataNodeIndex - data node i which to inject - the index is same as for getDataNodes() @param blocksToInject - the blocks @throws IOException if not simulatedFSDataset if any of blocks already exist in the data node
org.apache.hadoop.hdfs.server.datanode.SimulatedFSDataset.injectBlocks()

Examples of org.apache.hadoop.dfs.SimulatedFSDataset.injectBlocks()

    // Inject blocks
    // Now reset fsdataset with an initial block report (Use the blocks we got above)
  
   
    SimulatedFSDataset sfsdataset = new SimulatedFSDataset(conf);
    sfsdataset.injectBlocks(blockReport);
    blockReport = sfsdataset.getBlockReport();
    assertEquals(NUMBLOCKS, blockReport.length);
    for (Block b: blockReport) {
      assertNotNull(b);
      assertEquals(blockIdToLen(b.blkid), b.len);
