示例1: preDelete
import org.apache.hadoop.hbase.client.Delete; //導入方法依賴的package包/類
@Override
public void preDelete(final ObserverContext<RegionCoprocessorEnvironment> c,
final Delete delete, final WALEdit edit, final Durability durability)
throws IOException {
// An ACL on a delete is useless, we shouldn't allow it
if (delete.getAttribute(AccessControlConstants.OP_ATTRIBUTE_ACL) != null) {
throw new DoNotRetryIOException("ACL on delete has no effect: " + delete.toString());
}
// Require WRITE permissions on all cells covered by the delete. Unlike
// for Puts we need to check all visible prior versions, because a major
// compaction could remove them. If the user doesn't have permission to
// overwrite any of the visible versions ('visible' defined as not covered
// by a tombstone already) then we have to disallow this operation.
RegionCoprocessorEnvironment env = c.getEnvironment();
Map<byte[],? extends Collection<Cell>> families = delete.getFamilyCellMap();
User user = getActiveUser();
AuthResult authResult = permissionGranted(OpType.DELETE, user, env, families, Action.WRITE);
logResult(authResult);
if (!authResult.isAllowed()) {
if (cellFeaturesEnabled && !compatibleEarlyTermination) {
delete.setAttribute(CHECK_COVERING_PERM, TRUE);
} else if (authorizationEnabled) {
throw new AccessDeniedException("Insufficient permissions " +
authResult.toContextString());
}
}
}
示例2: preCheckAndDelete
import org.apache.hadoop.hbase.client.Delete; //導入方法依賴的package包/類
@Override
public boolean preCheckAndDelete(final ObserverContext<RegionCoprocessorEnvironment> c,
final byte [] row, final byte [] family, final byte [] qualifier,
final CompareFilter.CompareOp compareOp,
final ByteArrayComparable comparator, final Delete delete,
final boolean result) throws IOException {
// An ACL on a delete is useless, we shouldn't allow it
if (delete.getAttribute(AccessControlConstants.OP_ATTRIBUTE_ACL) != null) {
throw new DoNotRetryIOException("ACL on checkAndDelete has no effect: " +
delete.toString());
}
// Require READ and WRITE permissions on the table, CF, and the KV covered
// by the delete
RegionCoprocessorEnvironment env = c.getEnvironment();
Map<byte[],? extends Collection<byte[]>> families = makeFamilyMap(family, qualifier);
User user = getActiveUser();
AuthResult authResult = permissionGranted(OpType.CHECK_AND_DELETE, user, env, families,
Action.READ, Action.WRITE);
logResult(authResult);
if (!authResult.isAllowed()) {
if (cellFeaturesEnabled && !compatibleEarlyTermination) {
delete.setAttribute(CHECK_COVERING_PERM, TRUE);
} else if (authorizationEnabled) {
throw new AccessDeniedException("Insufficient permissions " +
authResult.toContextString());
}
}
return result;
