示例1: addSomeBlocks
import org.apache.hadoop.hdfs.server.datanode.FSDatasetInterface; //导入方法依赖的package包/类
int addSomeBlocks(FSDatasetInterface fsdataset, int startingBlockId) throws IOException {
int bytesAdded = 0;
for (int i = startingBlockId; i < startingBlockId+NUMBLOCKS; ++i) {
Block b = new Block(i, 0, 0); // we pass expected len as zero, - fsdataset should use the sizeof actual data written
OutputStream dataOut = fsdataset.writeToBlock(b, false, false).dataOut;
assertEquals(0, fsdataset.getLength(b));
for (int j=1; j <= blockIdToLen(i); ++j) {
dataOut.write(j);
assertEquals(j, fsdataset.getLength(b)); // correct length even as we write
bytesAdded++;
}
dataOut.close();
b.setNumBytes(blockIdToLen(i));
fsdataset.finalizeBlock(b);
