is that correct?
As I said there I don't personally have bandwidth to dig deep onto this, but
from your detailed explanation, it does seem to be a valid issue. I will let
[~shv] take a closer look.

>
> Although fast path tail use quorum read to pull edit log, it seem like can
> read uncommitted data in some corner case.
> Here is an example. Suppose we have three JN, their init state is:
>
> {code:java}
> epoch 1
> JN1 [1-3](in-progress)
> JN2 [1-3](in-progress)
> JN3 [1-4](in-progress)
> Note that, in epoch 1 txid 1-3 was committed, and txid 4 not.
> {code}
> When a failover occur, if a new writer cannot contact to JN3 for network
> partition, and finish the recovery stage, and write a new txid 4 in epoch 2,
> which value not equal to JN3's.
>
> {code:java}
> epcho 2
> JN1 [1-3](finalized) [4-4](inprogress)
> JN2 [1-3](finalized) [4-4](inprogress)
> JN3 [1-4](inprogress)
> Note that, in JN3 txid4's value not equal to other JN.
> {code}
>
> Now there is a read namenode to pull edits, and it contact to JN3 and JN2, it
> got majority response. But it got logs of same length but different
> content.And no more information to choose which log is right. If we choose
> JN3, we got meta data corruption.
> There is a test example patch [^example.patch] for running and debug.
> For fix it i think we should add finalized state to
> {{{}GetJournaledEditsResponseProto{}}}, so we can discard the fault log.

Do you not plan to add this method to ``FSNamesystemMBean``?
if no specific reason, we should add it there, this is quite specific to FSN

[jira] [Created] (HDFS-16495) RBF should prepend the client ip rather than append it.
Owen O'Malley created HDFS-16495: Summary: RBF should prepend the client ip rather than append it. Key: HDFS-16495 URL: https://issues.apache.org/jira/browse/HDFS-16495 Project: Hadoop HDFS Issue Type: Improvement Reporter: Owen O'Malley Assignee: Owen O'Malley Currently the Routers append the client ip to the caller context if and only if it is not already set. This would allow the user to fake their ip by setting the caller context. Much better is to prepend it unconditionally. The NN must be able to trust the client ip from the caller context. -- This message was sent by Atlassian Jira (v8.20.1#820001) - To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
