Work Description: lujiefsi opened a new pull request #2966:
URL: https://github.com/apache/hadoop/pull/2966
I have some doubt when i configurate secure HDFS. I know we have Service
Level Authorization for protocols like NamenodeProtocol,DatanodeProtocol and
so on.
But i do not find such Authorization for JournalProtocol after reading the
code in HDFSPolicyProvider. And if we have, how can i configurate such
Authorization?
Besides even NamenodeProtocol has Service Level Authorization, its methods
still have Permission check. Take startCheckpoint in NameNodeRpcServer who
implemented NamenodeProtocol for example:
public NamenodeCommand startCheckpoint(NamenodeRegistration registration)
throws IOException {
String operationName = "startCheckpoint";
checkNNStartup();
namesystem.checkSuperuserPrivilege(operationName);
......
I found that the methods in BackupNodeRpcServer who implemented
JournalProtocol lack of such Permission check. See below:
public void startLogSegment(JournalInfo journalInfo, long epoch,
long txid) throws IOException {
namesystem.checkOperation(OperationCategory.JOURNAL);
verifyJournalRequest(journalInfo);
getBNImage().namenodeStartedLogSegment(txid);
}
@Override
public void journal(JournalInfo journalInfo, long epoch, long firstTxId,
int numTxns, byte[] records) throws IOException {
namesystem.checkOperation(OperationCategory.JOURNAL);
verifyJournalRequest(journalInfo);
getBNImage().journal(firstTxId, numTxns, records);
}
Do we need add Permission check for them?
Please point out my mistakes if i am wrong or miss something.
