Flavio Junqueira commented on ZOOKEEPER-1453:
---------------------------------------------
I have just checked the ids of the servers, both traces and myid file, and the
id of the server 10.10.5.42 is wrong. From the traces, you can actually tell
that it was 3 and later switched to 2 after the reboot. Having two servers with
the same id seems to be causing the confusion you're observing here.

> Components: server

> Priority: Critical
> Attachments: 10.10.5.123-withPath1489.tar.gz, 10.10.5.123.tar.gz,

> See ZOOKEEPER-1449 for background on this issue. The main problem is that
> during server recovery
> org.apache.zookeeper.server.persistence.FileTxnLog.FileTxnIterator.next()
> does not indicate if the available logs are valid or not. In some cases (say
> a truncated record and a single txnlog in the datadir) we will not detect
> that the file is corrupt, vs reaching the end of the file.
