> Kerberized inotify client fails despite kinit properly
> ------------------------------------------------------
>
> Key: HDFS-13040
> URL: https://issues.apache.org/jira/browse/HDFS-13040
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Affects Versions: 2.6.0
> Environment: Kerberized, HA cluster, iNotify client, CDH5.10.2
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Major
> Attachments: HDFS-13040.001.patch, HDFS-13040.02.patch,
> HDFS-13040.03.patch, HDFS-13040.half.test.patch,
> TestDFSInotifyEventInputStreamKerberized.java, TransactionReader.java
>
>
> This issue is similar to HDFS-10799.
> HDFS-10799 turned out to be a client side issue where client is responsible
> for renewing kerberos ticket actively.
> However we found in a slightly setup even if client has valid Kerberos
> credentials, inotify still fails.
> Suppose client uses principal [email protected],
> namenode 1 uses server principal hdfs/[email protected]
> namenode 2 uses server principal hdfs/[email protected]
> *After Namenodes starts for longer than kerberos ticket lifetime*, the client
> fails with the following error:
> {noformat}
> 18/01/19 11:23:02 WARN security.UserGroupInformation:
> PriviledgedActionException as:[email protected] (auth:KERBEROS)
> cause:org.apache.hadoop.ipc.RemoteException(java.io.IOException): We

> During automatic edit log failover, we noticed that all of the remaining
> edit log streams are shorter than the current one! The best remaining edit
> log ends at transaction 8683, but we thought we could read up to transaction
> 8684. If you continue, metadata will be lost forever!

> Typically if NameNode has an expired Kerberos ticket, the error handling for
> the typical edit log tailing would let NameNode to relogin with its own
> Kerberos principal. However, when inotify uses the same code path to retrieve
> edits, since the current user is the inotify client's principal, unless
> client uses the same principal as the NameNode, NameNode can't do it on
> behalf of the client.
> Therefore, a more appropriate approach is to use proxy user so that NameNode
> can retrieving edits on behalf of the client.
> I will attach a patch to fix it. This patch has been verified to work for a
> CDH5.10.2 cluster, however it seems impossible to craft a unit test for this
> fix because the way Hadoop UGI handles Kerberos credentials (I can't have a
> single process that logins as two Kerberos principals simultaneously and let
> them establish connection)
> A possible workaround is for the inotify client to use the active NameNode's
> server principal. However, that's not going to work when there's a namenode
> failover, because then the client's principal will not be consistent with the
> active NN's one, and then fails to authenticate.
