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
