示例1: preGetOp
import org.apache.hadoop.hbase.client.Get; //导入方法依赖的package包/类
@Override
public void preGetOp(ObserverContext<RegionCoprocessorEnvironment> e, Get get,
List<Cell> results) throws IOException {
if (!initialized) {
throw new VisibilityControllerNotReadyException("VisibilityController not yet initialized");
}
// Nothing useful to do if authorization is not enabled
if (!authorizationEnabled) {
return;
}
Region region = e.getEnvironment().getRegion();
Authorizations authorizations = null;
try {
authorizations = get.getAuthorizations();
} catch (DeserializationException de) {
throw new IOException(de);
}
if (authorizations == null) {
// No Authorizations present for this scan/Get!
// In case of system tables other than "labels" just scan with out visibility check and
// filtering. Checking visibility labels for META and NAMESPACE table is not needed.
TableName table = region.getRegionInfo().getTable();
if (table.isSystemTable() && !table.equals(LABELS_TABLE_NAME)) {
return;
}
}
Filter visibilityLabelFilter = VisibilityUtils.createVisibilityLabelFilter(e.getEnvironment()
.getRegion(), authorizations);
