示例1: checkForReservedTagPresence
import org.apache.hadoop.hbase.client.Mutation; //導入方法依賴的package包/類
private void checkForReservedTagPresence(User user, Mutation m) throws IOException {
// No need to check if we're not going to throw
if (!authorizationEnabled) {
m.setAttribute(TAG_CHECK_PASSED, TRUE);
return;
}
// Superusers are allowed to store cells unconditionally.
if (Superusers.isSuperUser(user)) {
m.setAttribute(TAG_CHECK_PASSED, TRUE);
return;
}
// We already checked (prePut vs preBatchMutation)
if (m.getAttribute(TAG_CHECK_PASSED) != null) {
return;
}
for (CellScanner cellScanner = m.cellScanner(); cellScanner.advance();) {
Cell cell = cellScanner.current();
if (cell.getTagsLength() > 0) {
Iterator<Tag> tagsItr = CellUtil.tagsIterator(cell.getTagsArray(), cell.getTagsOffset(),
cell.getTagsLength());
while (tagsItr.hasNext()) {
if (tagsItr.next().getType() == AccessControlLists.ACL_TAG_TYPE) {
throw new AccessDeniedException("Mutation contains cell with reserved type tag");
}
}
}
}

}
示例2: preBatchMutate
import org.apache.hadoop.hbase.client.Mutation; //導入方法依賴的package包/類
@Override
public void preBatchMutate(ObserverContext<RegionCoprocessorEnvironment> c,

if (m.getAttribute(CHECK_COVERING_PERM) != null) {
// We have a failure with table, cf and q perm checks and now giving a chance for cell
// perm check

+ authResult.toContextString());
}

if (cf == null) {
cf = kv.getFamily();
}
Tag tag = new Tag((byte) 1, attribute);
List<Tag> tagList = new ArrayList<Tag>();
tagList.add(tag);
KeyValue newKV = new KeyValue(kv.getRow(), 0, kv.getRowLength(), kv.getFamily(), 0,
kv.getFamilyLength(), kv.getQualifier(), 0, kv.getQualifierLength(),
kv.getTimestamp(), KeyValue.Type.codeToType(kv.getType()), kv.getValue(), 0,
kv.getValueLength(), tagList);
