示例1: postInstantiateDeleteTracker
import org.apache.hadoop.hbase.regionserver.DeleteTracker; //导入依赖的package包/类
@Override
public DeleteTracker postInstantiateDeleteTracker(
ObserverContext<RegionCoprocessorEnvironment> ctx, DeleteTracker delTracker)
throws IOException {
// Nothing to do if we are not filtering by visibility
if (!authorizationEnabled) {
return delTracker;
}
Region region = ctx.getEnvironment().getRegion();
TableName table = region.getRegionInfo().getTable();
if (table.isSystemTable()) {
return delTracker;
}
// We are creating a new type of delete tracker here which is able to track
// the timestamps and also the
// visibility tags per cell. The covering cells are determined not only
// based on the delete type and ts
// but also on the visibility expression matching.
