示例1: init
import org.apache.hadoop.hbase.CellUtil; //導入方法依賴的package包/類
private void init() throws IOException {
final RestoreSnapshotHelper.RestoreMetaChanges meta =
RestoreSnapshotHelper.copySnapshotForScanner(
conf, fs, rootDir, restoreDir, snapshotName);
final List<HRegionInfo> restoredRegions = meta.getRegionsToAdd();
htd = meta.getTableDescriptor();
regions = new ArrayList<HRegionInfo>(restoredRegions.size());
for (HRegionInfo hri: restoredRegions) {
if (CellUtil.overlappingKeys(scan.getStartRow(), scan.getStopRow(),
hri.getStartKey(), hri.getEndKey())) {
regions.add(hri);
}
}
// sort for regions according to startKey.
Collections.sort(regions);
initScanMetrics(scan);
}
示例2: getSplits
import org.apache.hadoop.hbase.CellUtil; //導入方法依賴的package包/類
public static List<InputSplit> getSplits(Scan scan, SnapshotManifest manifest,
List<HRegionInfo> regionManifests, Path restoreDir, Configuration conf) throws IOException {
