ASF GitHub Bot logged work on HDFS-16004: ----------------------------------------- Author: ASF GitHub Bot Created on: 30/Apr/21 03:33 Start Date: 30/Apr/21 03:33 Worklog Time Spent: 10m 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. -- This is an automated message from the Apache Git Service.
